eBay Product Finder and Price Comparison

Compare all eBay listings for any product in one organized view on BuyMap. Built for resellers, collectors, and deal hunters.

Stop scrolling through hundreds of eBay listings trying to find the best deal on a product. Save time and money by seeing every seller on one page. This extension connects eBay to BuyMap, where all listings for a product get aggregated into a single organized view. HOW IT WORKS: On eBay search results: Click the "View All Listings" button next to any product to jump straight to BuyMap. On individual listings: Click the extension icon to grab the product's identifiers (EPID, UPC, ISBN, etc.) and search BuyMap. WHAT YOU GET ON BUYMAP: Filter by price, condition, listing age, buying format, best offer, seller rating, or location. See the full price range across all sellers so you know if you're getting a good deal. See seller descriptions without having to click into a listing. WORKS BEST FOR: Products with standard identifiers: electronics, books, video games, collectibles, branded items. If a listing has an eBay Product ID, UPC, ISBN, or part number, you're set. PRICING: The extension is free. BuyMap's free tier gives you 10 searches per day (20 when logged in). Paid plans available if you need more.
