If they buy a TV at WalMart because it's cheap and convenient, then they are stupid because it will probably break sooner than any other TV they could purchase. Then take it back and get another one.
But, of course, it won't break, because Wal-Mart sells the same stuff Target and Costco, and Sears and other retailers sell, only cheaper.
Have you even been in a Wal-Mart lately? You ought to go, then you'll realize you've been paying too much for some of the same stuff.
No, I haven't been to Walmart since the spring, looking in the garden section, but the issue is whether I take the time to research and buy American even if it means paying more. I have done that for shoes and clothes. I have been lax on computers, my last one was from Taiwan.
