Added something to my free chrome extension for Amazon Sellers, Replen Scout, this week that I've wanted for a while.

You're on a Target or Walmart product page, you right-click, and a side panel pulls up that same product on Amazon. It grabs the UPC off the store page and searches Amazon for it, so most of the time you're looking at the matching listing in a second or two with the sales rank, seller count, FBA sellers, and whether Amazon is on it.

Searching doesn't touch your Keepa tokens either. If you want the real fees and profit there's one button for that and it uses about one token.

Tested it on a bottle of Bachan's BBQ sauce at Target and the match came back in about a second and a half. Still completely free.
