Request accessWhat it does
Product page with history
Price, offers, stock and rank over time in step charts, with the buy box, the retailer’s own price and third-party offers on one timeline. Every figure shows its age.
Retailers side by side
The same product at the other US retailers we cover, matched by exact UPC or GTIN, with the price difference to the page you are on. No match is left empty, never guessed.
Finder
Saved views over the catalog, such as items that are cheaper at another retailer or where the retailer ran out and third-party prices rose.
Watchlist and alerts
Track the products and sellers you care about. Get an alert in the app or by email, instantly or as a daily digest, when a price drops, stock runs out or a seller changes.
Retailers: walmart.com, Walmart Business, Amazon, Target, Home Depot, Best Buy, eBay and TikTok Shop.
