When each of these first started doing third party marketplaces, it was a surprise. It's not like they announced to the world each time they dipped their toes into the market and each time they expanded it. I'm not american, but I was very surprised that Walmart had gotten into that business. It would surprise me if similar retailers in my country started this too.
