LemmeBuyIt — Price Compare

See which stores carry a product and compare prices while you shop.

LemmeBuyIt shows you cross-store price comparisons for the product you're already looking at. When you open a product page on a supported store, LemmeBuyIt reads the product's identity (its barcode/UPC, or the product ID in the page's URL) and looks up the same item at other retailers — then shows a small card with each store's price, so you can spot a better deal before you buy. Amazon and Walmart prices are shown alongside the others. How it works Open a product page at a supported store, a compact price-comparison card appears. Prices are sorted low-to-high, with the current page and the lowest price marked. Choose which stores to compare from the toolbar settings. Sign in with your free LemmeBuyIt account to use it. Free vs. Pro Free: full cross-store price comparison, up to 50 comparisons per month. Pro: unlimited comparisons, plus a 12-month Amazon price-history chart for the product. For Amazon sellers (optional): connect your own Amazon Seller account to see your own buy-box, FBA fees, and net margin for a product while you browse — your data, from your own authorized account. Privacy-first LemmeBuyIt reads only the product's identity and the (tracking-stripped) product URL — never your passwords, form fields, payment details, or personal content. LemmeBuyIt compares a product's price across stores while you shop, and shows connected Amazon sellers their own buy-box, fees, and margin. To keep those comparisons accurate, when you view a product page it also relays that product's identifiers and displayed price back to LemmeBuyIt so stale prices get refreshed for everyone. It works only on supported stores' product pages, and only when you're signed in. Some links are affiliate links.
