How do I fix a wrong Amazon match in Live search?

Live search finds each store product on Amazon by its barcode when it can. Without a barcode match, it makes a best guess from the product's title. A chip on the product tells you which: Best guess for a guess, Your pick for a listing you chose yourself.

Choose another listing

1. On the product, press Change. A product with no Amazon price yet shows Pick one instead.
2. The Which Amazon listing? window lists the listings that could be the same product, each priced against the store's price. Sort them by Best match or Best profit.
3. Press Choose on the right one. The listing in use now reads Keep.

Each listing shows its BSR, Est. Sales, Max Cost, Offers and profit, with links to View on Amazon and Request approval.

Go back to the UPC match puts the barcode match back.

Pack sizes

A store often sells one unit while the Amazon listing is a pack. When that happens, the product shows Buy 4 with the price of four units, because that's what one Amazon sale costs you.

If Amazon returns no listing at all for a product, it's usually the store's own brand, which isn't sold on Amazon.
