About Garage Sale Comp Checker
That $5 lamp might be worth $80. Garage Sale Comp Checker tells you in seconds. HOW IT WORKS 1. Snap a photo — or work down a whole table of finds; each item gets its own search. 2. We scan the web — reverse image search finds matching and similar listings across eBay, Poshmark, Etsy, Mercari, and more. 3. See real prices — every comp shows its price, source, and photo, with an average and high so you know the range at a glance. 4. Dig deeper — add keywords or limit results to specific sites to sharpen the match, and filter by source or price. BUILT FOR THE HUNT - Batch mode: keep shooting while searches run in the background - History: every check is saved to your account — photo, results, and prices - Works from your camera or your photo library Whether you're flipping for profit, pricing your own garage sale, or just curious what grandma's china actually goes for — check the comps before you buy or sell. Free during early access, with a monthly allowance of searches.
