Retail resale arbitrage check — "if I buy this at this price, what do I clear reselling it?" Live eBay ask comps (each linked to its listing; web-grounded fallback), fee math for eBay/Amazon/StockX/Poshmark/Mercari, profit + ROI at low/median/high comps, best-venue table, FLIP / THIN / PASS verdict. Returns INSUFFICIENT_EVIDENCE rather than an invented price.
