Question 1

What is an Amazon price glitch?

Accepted Answer

A price glitch is a price the retailer never meant to publish — a decimal in the wrong place, a bulk-upload feed that mapped the wrong field, a currency conversion applied twice. On the product page it looks identical to a planned promotion, so the only way to separate the two is price history. We score every Amazon UK listing against its own average over the previous 90 days, never against an RRP or a seller-supplied “was” price. The listings that come out as probable errors are collected on the Amazon UK price errors page.

Question 2

Does Amazon have to honour a price error in the UK?

Accepted Answer

Usually not. Under UK contract law the price shown on a product page is an invitation to treat, not a binding offer, so a retailer is generally entitled to cancel a transparently mispriced order before it is dispatched. What it cannot do is keep your money: if the order is cancelled, any payment taken has to be refunded. This is a general summary rather than legal advice — your consumer rights sets out where you stand.

Question 3

How do I find Amazon UK price errors?

Accepted Answer

By hand you would have to watch a listing's price history yourself and already know what it normally sells for. That is the part we automate: Amazon UK is rescanned every hour, each listing is scored against its own 90-day average, and anything that scores as a probable error is surfaced. Start with the price errors page for the top tier, the price glitch finder for how the scoring works, or the live feed for everything the scan has picked up.

Question 4

Are price glitch deals safe to buy?

Accepted Answer

You buy from Amazon UK, not from us — we list the price and link you across, so the payment, the delivery and the returns are Amazon's and carry your usual rights there. What actually goes wrong is cancellation rather than fraud: a retailer can cancel a transparently mispriced order before dispatch, and any payment taken has to be refunded. A low score is also a probability, not a verdict — a product genuinely being cleared out scores much the same as a mistake, which is why the methodology sets out the thresholds rather than promising a result.

Question 5

What is the Sniper Engine?

Accepted Answer

The Sniper Engine is the automated pipeline behind the site. It rescans Amazon UK every hour, scores each listing against its own average price over the previous 90 days, and sorts the result into tiers — an ordinary drop, a significant anomaly, or a probable pricing error. Anything that clears the threshold goes straight to the live feed with no human in the loop.

Question 6

How do you prevent fake or manipulated deals?

Accepted Answer

We compare every drop to the listing's own 90-day rolling average rather than to an RRP or a seller-supplied “was” price, because those are the two numbers a seller controls. The common trick — inflating a price briefly so a later discount looks enormous — shows up as a spike in that history and is filtered out. If it is not a real drop against the record, it does not reach the live feed.

Question 7

How is Glitchdeals different from a deal forum like HotUKDeals?

Accepted Answer

Different mechanism, not a better one. A forum depends on a person spotting a price and posting it, and a moderator approving it — which brings human judgement we do not have. Glitchdeals has no submission queue: the Sniper Engine rescans Amazon UK every hour and scores each listing against its own 90-day price history, so a drop is listed or not listed on the numbers. The trade-off is that the scan is hourly rather than instant, and it only covers Amazon UK.

Question 8

Why has a deal gone by the time I click it?

Accepted Answer

A pricing error exists because somebody at the retailer has not noticed it yet, so the window is set by their reaction time rather than by us. The scan is hourly rather than instant, which means an error can also be corrected before it ever reaches the feed. If you find a listing has already gone, report it from the deal page — enough independent reports in a short window mark it sold out and take it off the live feed.

Question 9

What is the 'Heat Score'?

Accepted Answer

The Heat Score is a heat reading that decays with age, so a drop people are still voting on stays near the top while older deals cool as they age. It orders the feed; it is not evidence that a price is genuine. Whether a listing is a probable glitch is decided by its price against its own 90-day average, not by its Heat Score.

Question 10

What is 'The Graveyard'?

Accepted Answer

The Graveyard is where a deal shows for about an hour after it ends, before it is archived. After that, the deal's own page is its record — the last recorded price, the 90-day average at the time and the recorded price history — for 180 days, and then it answers 410 Gone.

Question 11

Is Glitchdeals free to use?

Accepted Answer

Yes. The live feed, the Heat Score rankings and The Graveyard are free, with no paywalled tier. We believe in levelling the playing field and giving ordinary shoppers the same price history resellers work from.

Question 12

Do I need an account to browse?

Accepted Answer

No — anyone can browse the live feed. A free account is only needed to vote a deal hot or cold and contribute to the Heat Score. That is what ties one vote to one person per deal, so the ranking cannot be pushed around by repeat clicks.
