Every product's Amazon counterpart, with the reasons why
When you pick an eBay product that sells, SellerLibrary looks for its Amazon counterpart and scores it by model number, brand, variant and image similarity. Cost, eBay fees and net profit including shipping are worked out on the same screen.

The Amazon candidates of a product that sells are scored; the reasons for the best match are written out and net profit including eBay fees and shipping is worked out.

How it works

A score with its reasons
Model number, brand, variant and image are compared one by one, and you can always see where the score comes from. You can change the match or pick another Amazon product yourself; the final say is yours.
Prices for US delivery
Amazon prices, stock and shipping are read for the US delivery region selected in your Amazon session. An unknown region is not treated as verified. Prices and delivery conditions can vary by region.
Profit, with your target
Cost, eBay fees, shipping and your target margin are worked out together; if the suggested price falls below the target, the product is flagged.
Source tracking
The Amazon price and stock of live listings can be read again every 6 or 24 hours. A price below your profit target or a sold-out source comes to you as a notification.

YouIs buying on Amazon and selling on eBay allowed?
SellyeBay doesn't allow buying an item from another retailer and having it shipped straight to your buyer. SellerLibrary uses Amazon as a reference for price and cost; you're expected to ship from your own stock or an agreed supplier, and you confirm this before publishing.
SellyThe reasons behind the score are visible; you can change the match or pick another Amazon product yourself. No listing is published with a match you haven't approved.
SellyYes; the Amazon search runs through the extension. While a store is being scanned, Amazon matching can run at the same time.
