Arbitron

Forward a supplier email or upload an Excel or CSV list: Arbitron pulls out the products and purchase prices and calculates margin, ROI and monthly sales for your Amazon markets. Promising lines then go into the detail calculator.

Arbitron works the way wholesale sourcing works. Send it the supplier email, Excel or CSV, and it prices the whole list on the Amazon marketplaces you sell in, using your own fees, prep, storage and VAT. Filter to what looks worth buying, then open a product in the detail calculator to check fees, live offers, Buy Box share and Keepa history, and to see the risks: IP and private-label issues, Amazon on the listing, a monopolized offer, hard price swings, cheaper prices on Idealo.
