About GavelGap — GovDeals Auction Deal Scorer
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.
