What our price history can tell you
Our history begins when we first track an exact product. We cannot tell you what it cost before that date, or promise we cover every UK retailer.
Read the graph
The history records daily lowest observed in-stock item prices at the tracked retailers. A daily point is not a promise that price was available all day. Missing observations are gaps, not zero prices or proof of a stockout.
Read the homepage highlights
- Below yesterday’s tracked low: today’s current in-stock item price is below the lowest in-stock price we recorded yesterday.
- At our tracked low since a date: the current price matches or beats the observations in the available history. The date tells you how limited that comparison is.
- Restock observed: a tracked retailer changed from a fresh explicit out-of-stock observation to in stock. A failed request does not count as a stockout.
Retailer prices and stock can change between checks. Delivery charges may change the cheapest total. Treat the history as evidence for a decision, not a guarantee of a future price.
