We record every price ourselves, once a day, and only publish a movement when the current price is at least 5% below the median of the previous 30 days.
We started recording on 2026-08-23 and hold 24 days of history. No product currently meets that threshold, so there is nothing to show.
The panel on the back of a package carries more useful information than the marketing claims on the front, once you know which lines to check first.
