Terms of service

Last updated: 24 September 2026. These terms apply to every order placed on stackcouk.com on or after that date.

These terms are the contract between you and STACK when you buy from us. They cover who we are, how an order becomes a binding contract, what you pay, what happens if something goes wrong, and what each of us is responsible for.

They work alongside four other pages. Those five, together with the product page for the item you buy and your order and dispatch confirmations, make up the agreement between us — section 16 below sets that out in full, and section 3 explains why the product page is part of it:

Where a section below overlaps with one of those pages, we point to it rather than repeating it, so that there is only ever one version of each rule.

1. Who we are

STACK is a trading name of Harnek Padda, a sole trader established in Scotland, in the United Kingdom. A sole trader is an individual, not a company, so the contract you enter into is with Harnek Padda personally, trading as STACK. Our full trading and contact details are in section 1 of the Contact information page, and those are the details to use for any formal notice under these terms.

2. Who these terms apply to

These terms are written for consumers — individuals buying for purposes wholly or mainly outside a trade, business, craft or profession. If you are buying as a business, the parts of these terms that reflect consumer protection law will not apply to you, because that law protects consumers only. Section 15 below sets out what applies instead.

You must be at least 18 years old to place an order. That is a condition we set, not a statement about who is legally capable of contracting — in Scotland, where we are established, a person aged 16 or over has full legal capacity to enter a contract under the Age of Legal Capacity (Scotland) Act 1991, and we would rather say so than justify our own rule with a proposition that is not true in our own jurisdiction. We set 18 because we take card payments, and because the product is an electrical item that the buyer installs themselves; both work better with an adult account holder. By placing an order you confirm that you are 18 or over. We do not ask your age at checkout and we do not otherwise collect it. Section 8 of our Privacy Policy explains why our website is not directed at children.

3. The product we sell

STACK currently sells a single product line: a smart, screen-synced RGB monitor light strip. The strip attaches to a monitor and changes colour in response to what is displayed on the screen, using the sync method described on the product page.

Product images, colour representations and animations on this website are illustrative. Colour output varies with your monitor, your room lighting and your own device settings, and photographs of lighting products in particular can never be an exact match for what you will see in your room. Nothing on the product page is a promise that the light will look identical to a photograph. The written specification on the product page is the specification that forms part of our contract.

If the product relies on a companion app, a desktop application, or a device that captures what is shown on your screen, the product page will say so before you buy, and section 6 of our Privacy Policy explains what that software does and does not send, and to whom.

4. Price and payment

Prices are shown in pounds sterling. We are not currently registered for VAT, so no VAT is added to your order and no VAT is shown separately — the figure on the product page is the whole figure. If our VAT position changes we will update this section and the Contact information page, and VAT will be shown separately from that point on. The price you pay is the price displayed on the product page at the moment you place your order.

Delivery within the United Kingdom is free, as set out in section 2 of the Shipping Policy. The price on the product page is the total price you pay: no delivery charge, handling fee, packaging fee or service charge is added at any stage of checkout. Nothing further becomes payable simply because you have bought from us. The only sums that can arise after checkout are the actual costs described in section 13 below — a failed second delivery attempt, or a cost caused by an incorrect delivery address — and neither is a fee: each is limited to what we have genuinely lost, we tell you the amount before we charge it, and section 11 of the Shipping Policy lets you take a refund instead of a second attempt. We do not present an initial price that cannot actually be obtained. This matters because the unfair trading provisions of the Digital Markets, Competition and Consumers Act 2024, which came into force on 6 April 2025 and replaced the Consumer Protection from Unfair Trading Regulations 2008, specifically prohibit that kind of drip pricing.

We take payment at the point you place your order. Payment is processed by the payment providers enabled at our checkout, which are shown to you on the payment page before you pay. We never see or store your full card number; section 4 of our Privacy Policy explains exactly what payment information reaches us and what does not.

If a price is obviously wrong — for example if a decimal point has slipped — and the error is one you could reasonably have recognised as a mistake, we are not obliged to supply the product at that price. We will contact you, explain, and either ask whether you wish to proceed at the correct price or cancel the order and refund you in full.

5. How the contract is formed

The product listing is an invitation to buy, not an offer. Your order is the offer. Placing an order does not by itself create a contract.

After you order, you will receive an automated email acknowledging that we have received it. That acknowledgement is not acceptance. A binding contract comes into existence only when we send you a separate dispatch confirmation, at which point we accept your offer.

We may decline an order, and because no contract exists until dispatch confirmation, declining one is not a breach of contract. We may decline where the product is out of stock or has been withdrawn; where there is a pricing error of the kind described in section 4 above; where a payment is declined, reversed, or flagged by our payment provider or fraud screening; where the delivery address is one we cannot ship to under section 1 of the Shipping Policy; where the billing and delivery details do not match in a way we cannot resolve; where the quantity or pattern of ordering suggests the goods are for resale rather than personal use; or where the order comes from an account or address associated with conduct described in section 12 below.

If we decline, we will tell you and refund any payment in full, promptly. We are not obliged to give a detailed reason where doing so would reveal how our fraud screening works.

We may also cancel an order after accepting it if we discover any of the above after the fact, or if our supplier is unable to fulfil it. In that event we refund in full, and section 10 of the Return and refund policy applies.

A refund is not the end of it where our supplier let us down. Returning your own money is not compensation. Choosing our supplier was our decision, not yours, which is why section 14 below deliberately does not treat supplier failure as an event outside our control. So if we cancel an accepted order because our supplier could not fulfil it, and that cancellation causes you a loss beyond the price — you bought elsewhere at a higher price, or you paid for something to make the light work that is now useless — tell us. We will look at it properly rather than pointing at the refund and treating the matter as closed.

Two limits on acceptance-on-dispatch, so that it cannot work against you. First, we will either dispatch your order or tell you we are declining it within 7 working days of receiving it. If we have done neither by then, you may cancel and we will refund you in full, whatever the reason for the delay. Second, we treat the 30-day statutory delivery deadline in section 5 of the Shipping Policy as running from the day you placed your order, not from the day we dispatched it. We say so expressly because a deadline that only begins once we choose to act would leave you without a remedy in exactly the situation where you most need one, and we take your money at the point of order rather than at dispatch.

Correcting a mistake in your order. Before you place it, you can review and change everything — quantity, address, payment method — using the basket and the checkout screens, and you can go back a step at any point. If you spot an error after ordering, email us immediately; we will correct it if the order has not yet gone to our supplier, and section 10 of the Shipping Policy explains why address errors in particular need to reach us fast.

Language and records. This contract is concluded in English only. We keep a record of your order, and your confirmation and dispatch emails are your own copy of it — we suggest saving them, along with these terms, because we do not guarantee to make an archived copy available to you on request indefinitely.

6. Delivery

Everything about delivery — where we ship, what it costs, how long it takes, where your order ships from, customs charges, who carries the risk in transit, and what happens if a parcel does not arrive — is set out in the Shipping Policy. That page forms part of these terms.

We have put all of it in one place rather than summarising it here, because a short summary sitting alongside a longer version is how two versions of the same rule end up contradicting each other. Where a contract term is ambiguous, the law requires it to be read in the way most favourable to you, so a contradiction is not a loophole we would win.

Two points from that policy are load-bearing for this contract and are repeated here only as signposts. The statutory 30-day delivery deadline is at section 5 of the Shipping Policy. The fact that goods remain at our risk until they reach you, so that a lost parcel is our loss and not yours, is at section 8 of that policy.

7. Cancelling, returning and faulty goods

You have a legal right to cancel a distance purchase within 14 days without giving a reason, and separate legal rights if the goods are faulty, not as described, or unfit for purpose. Both sets of rights, and how to use them, are set out in full in the Return and refund policy. That page forms part of these terms.

We have deliberately put all of it in one place rather than summarising it here, because a short summary of consumer rights alongside a longer version is how contradictions get created, and where a term is ambiguous, the law requires it to be read in the way most favourable to you.

8. Product safety and correct use

The light strip is an electrical product. Install and use it in line with the instructions supplied with it, and with any power supply or adapter supplied with it. Do not cut, modify, rewire or submerge the strip, do not use it with a third-party power supply of a different rating, and do not install it in a location the instructions say is unsuitable.

Damage caused by modification, by use contrary to the instructions, or by connecting the product to an incompatible power source, is not a manufacturing fault and is not covered by the remedies in section 5 of the Return and refund policy. This does not narrow your legal rights where the product was genuinely faulty when it reached you; it simply reflects that those rights apply to faults, not to accidental damage.

If you become aware of a safety issue with a product bought from us, tell us immediately using section 2 of the Contact information page. We will respond to any report of a safety issue, and we will not treat it as a routine complaint.

Recycling at the end of the product's life. Electrical products must not be put in ordinary household waste. A product marked with a crossed-out wheeled bin symbol should go to a separate collection point for recycling when you are finished with it. Recycling keeps hazardous substances out of landfill and allows the materials to be recovered, rather than leaving them to leach out of a landfill site.

To find your nearest collection point, use the service for where you live: recyclenow.com in England, walesrecycles.org.uk in Wales, zerowastescotland.org.uk in Scotland, or nidirect.gov.uk in Northern Ireland, which has a page specifically on recycling electrical items. Your local council's website will also list what its sites accept.

Our own take-back offer. We are members of the Distributor Takeback Scheme (DTS), the industry scheme that lets online-only sellers of electrical and electronic equipment meet the take-back duty in the WEEE Regulations 2013 without running our own collection points. Because we're a member, you don't need to send your old item back to us — use one of the free recycling points listed above instead.

If you would like advice on disposing of a STACK product, email us and we will help.

9. Your account and use of this website

You can order as a guest or create an account. If you create one, keep access to the email address it uses secure and do not let anyone else use your account, because signing in works by a one-time code sent to that address rather than by a password. Tell us promptly if you think someone else has gained access to it.

We may suspend or close an account only on the same reasonable and objective grounds set out in section 12 below: fraudulent use, repeated use to place orders we have declined under section 5 above, or use to abuse the returns process. Suspicion alone is not enough. We will tell you what the grounds are and you can respond, and closing an account does not affect any order already accepted, any refund already owed to you, or any statutory right attaching to something you have already bought.

What we store against your account, and how long we keep it after you close it, is set out in sections 3 and 7 of the Privacy Policy.

We try to keep the website available and accurate, but we do not promise it will be uninterrupted or error-free. We may change, suspend or withdraw any part of it, and we may change the products we offer and their prices, without notice. A change to a price or a product does not affect an order we have already accepted under section 5 above.

You may not use the website unlawfully, attempt to gain unauthorised access to it, scrape it at a scale that affects its operation, or introduce anything malicious into it.

The text, layout and the STACK name and branding on this website belong to us. Product photographs and other product imagery are either ours or are used with the permission of the party that owns them. You may view and print any of it for your own personal use. You may not reuse any of it commercially without written permission — ours for the material we own, and the rights holder's for anything we do not.

10. Marketing emails and reviews

We send marketing emails to people who have asked to receive them, and to our own customers about the same or a similar product unless they have told us not to. Section 5 of the Privacy Policy explains the difference and the lawful basis for each. Every marketing email contains an unsubscribe link, and unsubscribing takes effect promptly and at no cost to you. Unsubscribing from marketing does not stop emails we have to send about an order you have placed, such as a dispatch confirmation or a refund notification, because those are part of performing the contract rather than marketing. Section 5 of the Privacy Policy covers this in detail.

If you submit a review or any other content, you confirm it reflects your genuine experience of a product you actually bought. We do not write reviews ourselves, do not commission or pay for reviews, and do not publish reviews we know or ought to know are fake. Submitting or commissioning a fake review is prohibited by the Digital Markets, Competition and Consumers Act 2024.

We may decline to publish, or may remove, content that is unlawful, abusive, discloses someone else's personal information, or is not about a genuine purchase. We do not remove a review simply because it is negative. By submitting content you give us permission to display it on the website in connection with the product it concerns.

11. Fraud, chargebacks and payment reversals

Orders are screened for fraud by our payment providers. We may hold an order, request confirmation of identity or of the billing address, or decline it under section 5 above. We do this to protect cardholders as well as ourselves, and we will not be pressured into releasing an order that has failed screening.

If a payment is reversed, charged back, or reclaimed after we have dispatched an order, the goods remain our property until we have been paid in full, and we may require their return at our cost.

When we may treat the sum as a debt, and when we may not. We may recover the money from you as a debt only where you kept the goods and the reversal was not something you were entitled to. We will not do so where your card was used by someone else without your authority, where the reversal reflected a refund you were genuinely owed, or where your bank or card issuer reversed the payment for reasons of its own. In those situations the person who owes us nothing is you, and a term that made you liable for something outside your control — while we carried none of the risk — would sit squarely on the list of terms Schedule 2 of the Consumer Rights Act 2015 treats as potentially unfair. If you are the victim of card fraud on an order placed in your name, tell us and we will treat you as a victim of it too, not as a debtor.

If you believe a charge is wrong, contact us before raising a chargeback with your bank. We will investigate and, where you are entitled to money back, refund you directly and usually faster than a chargeback would. Raising a chargeback instead of contacting us is your right and we will not penalise you for exercising it — but where a chargeback is raised on a ground we can show to be untrue, for example non-delivery of goods that were delivered, we will defend it with the evidence we hold, and we may decline to accept future orders from you under section 5 above.

We report suspected payment fraud to our payment providers and, where appropriate, to the police or Action Fraud. Nothing in this section affects your rights against your card issuer.

12. Abuse of these rights

The consumer rights described in these terms and in the Return and refund policy are given to you by law and we will honour them fully. They exist to protect genuine purchases. They are not designed to support a pattern of conduct intended to obtain goods without paying for them.

We may decline future orders, close an account under section 9 above, or require additional verification before accepting an order, where we have reasonable and objective grounds to believe that a person has repeatedly claimed non-delivery of parcels that carrier evidence shows were delivered; has repeatedly claimed faults that examination does not support; has used the cancellation right as a way to use products and return them in a condition that has lost most of their value, in circumstances where the deductions in section 2 of the Return and refund policy would be the appropriate response; has supplied false identity, address or payment information; or has abused, threatened or harassed us.

Two things this section does not do. It does not allow us to refuse a valid cancellation or a valid faulty-goods claim on an order we have already accepted — those rights are statutory and survive any view we take of your conduct. And it does not operate on suspicion alone; we need reasonable grounds, we will tell you what they are, and you can respond.

Declining to trade with someone in future is lawful. Refusing them the rights attached to a purchase they have already made is not, and we do not claim the power to do it.

13. Recovering costs you cause us

Where you cause us a direct and quantifiable cost through something within your control — a delivery address error under section 10 of the Shipping Policy, or a failed second delivery attempt under section 11 of that policy — we may ask you to reimburse that actual cost. We will tell you the figure and how we arrived at it, and you can dispute it.

We will not take it out of a statutory refund. Where you are cancelling under section 2 of the Return and refund policy, or rejecting faulty goods, the law limits what may be deducted from your refund and a cost of this kind is not on that list. So this is a separate claim we would have to make and justify, not something we quietly net off. The only deduction we make from a cancellation refund is for goods whose value you have reduced by handling them beyond what a shop would allow, which section 2 of that policy sets out in detail.

We will only ever recover what we have genuinely lost. We do not charge restocking fees, administration fees, handling fees or any other charge designed to make a return less attractive than it should be, because a fee of that kind imposed on a consumer exercising a statutory right is an unfair term and would be unenforceable.

14. Our responsibility to you, and events outside our control

If we fail to comply with these terms, we are responsible for loss or damage you suffer that is a foreseeable result of our breach. Loss or damage is foreseeable if it is obvious that it will happen, or if at the time the contract was made both of us knew it might happen.

We do not exclude or limit our liability in any way where it would be unlawful to do so. That includes liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, for defective products under the Consumer Protection Act 1987, and for breach of the rights you have in goods under the Consumer Rights Act 2015 — including that goods must be of satisfactory quality, fit for purpose, as described, and match any sample or model shown to you.

We are not responsible for business losses. Our products are supplied for domestic and private use, and if you use one for any commercial or business purpose we have no liability to you for lost profit, lost business, business interruption or lost business opportunity.

We are not liable for a delay or failure to perform caused by something genuinely outside our reasonable control, such as a carrier disruption, a customs delay, extreme weather, industrial action or a change in the law. We deliberately do not include our supplier's failure or insolvency in that list. Who we buy from is our decision, not yours, and a term that let us escape liability because the supply chain we chose let us down would be an unfair term rather than a real excuse. If such an event occurs we will tell you and do what we reasonably can to reduce the delay. If the delay becomes substantial you may cancel the order and we will refund you in full. This does not override the 30-day delivery backstop at section 5 of the Shipping Policy, which is a statutory right and applies regardless of the cause of the delay.

15. If you are buying as a business

Where you buy as a business rather than a consumer, the consumer-law rights described in these terms and in the Return and refund policy do not apply to you, because those rights are given to consumers by statute. In that case: there is no right to cancel under section 2 of that policy; our total liability to you for any order is limited to the price you paid for that order; and we are not liable for any indirect or consequential loss.

As to the quality of the goods, the terms implied by the Sale of Goods Act 1979 are excluded only so far as it is reasonable to exclude them under the Unfair Contract Terms Act 1977. We do not claim a blanket exclusion, because a blanket exclusion between a small trader and a business buyer would very likely fail the reasonableness test, and a term that fails leaves us with less protection than a proportionate one that holds. The express specification on the product page applies in any event.

Nothing in this section limits liability that cannot lawfully be limited.

16. Changes, complaints and the law that applies

We may update these terms. The version that applies to your order is the version published on this page at the time you placed it, and we date every version at the top of the page for that reason. A change we make later does not alter a contract already formed.

If you are unhappy with anything, please use the complaints procedure at section 4 of the Contact information page. Section 5 of that page explains our position on alternative dispute resolution, and section 6 lists free, independent sources of consumer advice.

This contract is governed by the law of the part of the United Kingdom in which you live, and you may bring legal proceedings in the courts of that part. We are established in Scotland, so proceedings against us may also be brought in the Scottish courts.

If any section is found to be unenforceable, the rest continues to apply. If we delay in enforcing a term, that is not a waiver of our right to enforce it later.

These five pages — these terms, the Shipping Policy, the Return and refund policy, the Privacy Policy and the Contact information page — together with the product page for the item you bought and your order and dispatch confirmations, are the agreement between us. The product page is included deliberately: section 3 above says the written specification there forms part of the contract, and it would be incoherent to incorporate it in one section and exclude it in another. Beyond those, nothing said in an advertisement, a social media post or a message from us forms part of the contract unless it is repeated in one of them or confirmed in writing. Nothing in this paragraph limits our liability for anything we have told you fraudulently, or excludes your rights where a public statement we made about the goods was part of why you bought them.
