Asks, sold comps, and when each marketplace wins
StockX is the deadstock ask/bid board. eBay is the flexible market — new, used, and long-tail — with sold comps that anchor deal scores. Smart buyers use both.
What StockX is good for
Authenticated deadstock, clear size selection, and a visible ask/bid. Best when you already know the style code and want a clean pair at a known size.
What eBay is good for
Price discovery, auctions, used/VNDS, and sold comps. GrailHawk's live rankings and size alerts run on eBay Browse today. Sold comps beat optimistic asks.
How GrailHawk ties them together
Style-code guides show live eBay listings with size-aware alerts. When StockX Impact is enabled, compare CTAs deep-link to StockX search for the same SKU. No scraped or invented asks.

FAQ
Is StockX always more expensive?
Not always. Fees, shipping, and size liquidity differ. Compare all-in and recent solds for your size.
Does GrailHawk scrape StockX?
No. Priced StockX rows come from affiliate product feeds or CSV import after Impact enrollment. Compare links use tracked deep links.
