FlipFind — Fair Value Overlay

See fair market value and flip margin on marketplace listings while you browse.

FlipFind — Fair Value Overlay for Marketplace Listings FlipFind shows you the real fair market value of items on Craigslist, Facebook Marketplace, and OfferUp — right as you browse. No more opening new tabs, searching eBay, and guessing whether that "deal" is actually a deal. What it does: When you're looking at a marketplace listing, FlipFind automatically analyzes the item title and price, pulls comparable sold prices from eBay and Craigslist, and calculates a fair value range. A clean badge appears next to the listing showing: * Fair value range — what the item actually sells for * Margin % — how far below market the asking price is (green = great deal, red = overpriced) * Confidence score — based on how many comparable sales were found * Fire signals — 🔥 flags for standout deals worth grabbing fast Why install it: * Stop overpaying. Know instantly if a listing is priced above, at, or below market value. * Find flips faster. Spot underpriced items with real margin data, not gut feelings. * Zero workflow change. The badge appears automatically — no buttons to click, no separate app to open. * Free to use. 50 fair-value lookups per day at no cost. Pro plan available for heavier users. How it works: FlipFind cross-references the listing title against real eBay sold data and Craigslist comparable listings, builds a fair value range from those comps, and calculates your flip margin. The more comps found, the higher the confidence — and low-confidence results are hidden so you're never misled by thin data. Works on: Craigslist · Facebook Marketplace · OfferUp
