UK Price Tracker
We record product prices across major UK retailers on a schedule and keep the history. This page is a live, public view of what we track and where prices are falling right now — over a rolling 90-day window. Free to read, free to cite.
Price history is building.
Our scheduled price snapshots have started recording. As the history accrues over the coming days, this page will fill with the products and retailers we track and the biggest live price drops. Check back soon, or browse current deals.
Methodology
Prices are captured on a recurring schedule from retailer product feeds and public APIs, then stored as time-series observations. The figures above cover a rolling 90-day window and are recomputed hourly. “Was” is the first price we observed for a product in the window; “Now” is the most recent. We don’t adjust for promotions or bundles — the numbers are exactly what we recorded.
