Link unknown product codes to your products

A merchant sends a sale for a product code you never entered. Often the product is already in your catalog, just without that merchant's ID, and the only offer used to be creating a second copy named after the code.
The enemy is one offer split across two products.
The Create Missing Product suggestion now offers Link to existing product next to Create. It lists your products that look like the one the merchant sent, with the reasons: the same price, words the names share, and no ID for that merchant yet. One is preselected only when it clearly matches; otherwise you pick. Products that already carry a different ID for that merchant are never offered. Linking saves the code on the product, closes duplicate suggestions and the alert for that code, and records the JVZoo and ClickBank sales that came in without a product on it. Creating a product now starts from the name the merchant sent.

Try it: when a sale arrives for a code you have not set up, open Alerts (the star in the top bar), click Review on the Create Missing Product fix, check the suggested product and click Link product.
