How the eBay Sniper works
We scan eBay every 30 minutes for PSA 10s priced below market and rank them by margin.
Understanding bid analysis
The bid analysis panel breaks down market value, fees, max bid, and expected profit.
PSA cert verification
Verify a PSA slab's cert number against PSA's database from inside the lightbox.
Why am I seeing no deals?
Common causes: filters too strict, watch list empty, or eBay rate-limiting.
Sold listings data
How we pull, cache, and surface eBay sold listings across the app.
Supported grading companies
Mintlytics tracks PSA, BGS, CGC, and TAG slabs across every feature.
Adding cards to watch
Build a Sniper watch list by adding cards from any detail page. Grade-specific.
Setting up deal alerts
Email notifications when a new Sniper deal lands. Pro plan only.
eBay fees calculation
We use a flat 12.9% final-value fee. Shipping is handled separately.
Max bid calculator
Auction-only. Highest bid you can place and still hit your target margin.
Why was my deal marked expired?
Deals expire when the eBay listing ends, sells out, is delisted, or 404s.
