Walmart and Target are actually much worse. Target is perhaps the worst of all, believe it or not. If a scammer creates a listing for a particular UPC, they own it within the Target system basically forever. Even if you approach Target as the legitimate brand and try to take control of the listing they refuse and then try to essentially extort you. They tell you that you can essentially “stop the bleeding” by signing up with a certain third party vendor that charges thousands a month so you can list on Target. And even if you do, that product listing still remains controlled by someone else. They wanted it to be a kind of “gold rush” where brands would run to sign up for fear of losing the ability to sell their products to third parties.
