Todd, I think the issue is with the language of their information (calm down...I'm not accusing you of not knowing how to read :-)). As I read it, they mean 1/2 were purchases from companies making goods specifically to WalMart's specs, sort of like an OEM manufacturer, while the other half from companies selling them general merchandise that was already being made for others. Basically I mean half made to order and half bought off the shelf so to speak. In my case (A Japanese company with distributors in the U.S. and Canada) we wouldn't fall under either category even though the specific goods we sell WalMart are made in China.
That depends. If they buy the goods from the Canadian or US distributors then you might be correct.
If they buy them from your plant in China, then I am correct. Either way, they don't sell 100% Chinese goods.
According to walmartfacts.com they bought $137.5 billion from US companies. Is zero of that sourced from Chinese companies? I don't know. But I'm open to new sources (linked of course) unlike some dingbats around here.
