How price history protects you from a fake sale

A discount label tells you two numbers: what the retailer says the price was, and what it is now. It doesn't tell you what the price has actually been. That's the number that matters, and it's the reason every product page on this site carries a price history.

What we record

Every listed product's price, every day, from the retailer's own feed. Not scraped, not estimated. When you open a deal page, you see the line: was £749 on 30 August, £699 today, lowest we've seen. Or: held at £699 for 14 days. Or: was £649 on 2 September, now £699 — which is a price rise dressed as a deal.

Why it works

Retailers can set "was" prices. They can't change what they charged last Tuesday. A history of actual prices is the one reference the label can't manipulate. A "lowest we've seen" on a product tracked for a month is a real signal. On a product tracked for a year, it's close to certainty.

What it shows about the market

After a few weeks, patterns appear. Some products bounce between two prices on a fortnightly cycle — that's a rotation, and the low point comes round again. Some drift down slowly — that's a range change coming, and the floor is lower. Some spike after a competitor's sale — that's the market re-pricing. You learn a product's rhythm, and you buy on the beat.

Its limits

We started recording in September 2026. A product with three data points has a short history and the "lowest we've seen" means less. The line on the page says how many days we've tracked it; read the signal in that light. It gets better every day, and we don't reset it.

How to use it

Find the product. Read the history. If it's at a low, buy. If it isn't, press "Watch this price" and we'll email you when it drops. That's the whole method.
