Scores every GovDeals lot as you browse: landed cost, eBay sold-comp resale & profit gap. Know if it flips before you bid. Know if a GovDeals lot will actually flip — before you bid. GavelGap adds a sidebar to every GovDeals auction listing and does the reseller math for you in real time, so you bid on numbers instead of the opening price: • LANDED COST — winning bid + buyer's premium + estimated shipping, so you see the true cost to acquire, not the teaser opening bid. • RESALE ESTIMATE — what the item actually sells for on the open market, from eBay sold comparables (Pro) plus market valuations for vehicles and precious metals. • THE PROFIT GAP — resale minus landed cost, with a clear buy/pass verdict, so you stop overpaying on lots that won't flip. • FRICTION FLAGS — pickup-only, untested/for-parts, BIOS-locked, missing titles, freight-only, and other margin-killers, surfaced automatically. Works across categories resellers source from GovDeals: IT and electronics, laptops and phones, vehicles, heavy equipment, and precious metals. FREE: scores, friction flags, and the landed-cost math on the listing you're viewing — forever. PRO: the eBay sold comps behind every number, GovDeals bidding history, a deal feed that watches listings for you, and alerts. Built for people who resell government surplus and don't want to lose money on an as-is lot. Independent third-party tool. Not affiliated with, sponsored by, or endorsed by GovDeals, Liquidity Services, or eBay. All analysis happens in your browser; GavelGap never bids or buys on your behalf.
