FairSift

Compare product prices across Amazon and eBay, get price-drop alerts, and track price trends over time.

Never overpay again. FairSift is a free Chrome extension that checks prices for you while you shop — right on the Amazon or eBay product page, nothing to configure. HOW IT WORKS 1. Install FairSift. It activates automatically on Amazon and eBay product pages. 2. Shop like normal. FairSift reads the product title and price from the page you're already viewing. 3. See the verdict instantly: the best live price we can find, how it compares, and exactly how much you'd save or overpay. KNOW IT'S FAIR Every check comes with a straight verdict — Real Deal, Fair, or Fleeced Territory — computed against recent observed prices for the same product, not from a fake "was" price somebody invented. FairSift records anonymous price observations as people shop, so the verdicts get smarter every day. Browse public price checks for hundreds of real products at getfairsift.com/prices. MORE STORES ON THE WEB At getfairsift.com/compare you can paste any product name or link and check eBay alongside Walmart and Best Buy prices, scan a barcode, or search by photo. FREE FOREVER FOR SHOPPERS Unlimited price comparisons. No account required. No cost — ever. No ads in the popup. PRICE-DROP ALERTS Set a target price on any product and FairSift emails you the moment it drops. A free account includes 5 active price watches. FOR SELLERS: FAIRSIFT DATA Sellers and resellers: FairSift Data turns our growing cross-store price-observation dataset into demand signals, price trends, and competitive spreads — $9.95/month, a fraction of legacy tracker pricing. See getfairsift.com/pricing. PRIVACY FairSift reads only the product title and price from Amazon and eBay product pages in order to run the comparison. Observations are stored with no user identifiers. No browsing history is collected or sold — ever. Know it's fair.
