A lot this depends on what they mean by marketplace. Amazon (and Walmart I think) don't just buy and sell stuff. They also let you sell stuff through them. Target on the other hand have an online store but you are always buying from Target. So if the law considers "online marketplace" from "online store" then it doesn't apply to Target.
