How we read this category

Every figure above comes from prices we observed ourselves on retailers’ public product data. A “real drop” means today’s best verified price is below the median we recorded for that product over the last 90 days — not that a store put a sale badge on it.

0 of the 137 products here currently meet our quality bar for search indexing. The rest stay visible to you but are excluded from search engines until they have enough verified offers and history to be genuinely useful.

How we calculate this

Where prices come from. We read the product data each retailer publishes on its own site, unhurriedly and within the rules that retailer sets. We never work around an access control and we never buy collected data of uncertain provenance.

What “verified” means. An offer can win best price only if it is inside our freshness window, matched to the exact variant, in stock, and free of an unresolved price anomaly. “Best verified price” means lowest among the fresh offers we track — not the lowest price on the internet.

How history works. Every price we observe is stored with its source and timestamp. Daily market low, median and high come from those observations, so the price history on this page is ours, not a retailer’s claim.

What we exclude. Stale offers, mismatched variants, bundles compared against single items, and prices that move implausibly without corroboration from another store.

Images. Product photographs come from the retailer they sit beside, loaded from their own image host. We do not re-host them and claim no rights in them.
