Crazy Vendor turns your phone into a sourcing tool. Scan a product barcode in any store and instantly see whether it is worth buying to resell on Walmart. What a single scan gives you: • Sells for — the current Walmart buy box price • Total fees — referral, WFS fulfilment, storage and inbound shipping, itemised • Profit, ROI and margin — enter what you pay, see what you keep • Competition — every seller on the listing with price, stock and fulfilment method, buy box marked • Price history — 90 days of buy box movement, broken down month by month • Listing signals — Walmart's own badges, rating and review count Point the camera at a UPC, EAN, or the item number printed on a shelf label. The product opens in seconds. Built for resellers who source in stores and need the numbers before the item goes in the cart — not after.
