What GavelGap catches

Every listing gets the skeptical treatment.

🚫
Shipping & Removal Traps
No combined shipping. Buyer-arranged freight. Third-party removal. Appointment-only pickup. Tight removal deadlines. All the clauses that turn a "good deal" into a logistics nightmare.
⚠️
Condition & Quality Risk
Missing hard drives. Untested. As-is. For parts. BIOS-locked. Power-on-only testing. The stuff that eats into your resale value after you've already paid.
💰
Landed Cost Math
Hammer price + buyer premium + shipping + friction penalties = what you're actually paying. The Deal Score shows you the margin that's left after the hidden costs.
📊
Sold Comps, Not Vibes
Resale estimates based on actual completed eBay sales — not active listings, not asking prices. If the comps are thin, we tell you that too.
🔍
Lot Ambiguity Detection
Mixed pallets. Unknown quantities. "See photos for details." No manifest. When the listing is vague, GavelGap flags exactly what's missing.
🏛
Seller Signal Analysis
Government agency or private liquidator in a government hat? Contractor-managed sales, consignment language, and extra fees get flagged.

GavelGap is not trying to find you deals. It's trying to stop you from losing money on deals that look good until the fine print arrives.

avg listing: 4.3 friction flags · $185 in hidden costs

We scanned 200+ real GovDeals IT listings during development. Most of those costs were buried in special instructions that nobody reads at 2am.

The most useful thing the tool does is tell you not to buy something. If that sounds like what you need, you're the person we're building this for.
