I don’t disagree with the data cited in the link you posted. I do not believe WalMart shoppers are representative of the country as a whole. I do not shop at WalMart. Haven’t since they went primarily a distributor of Chinese goods. I also do not shop at Sam’s. Your identifying yourself as a WalMart shopper makes me wonder...WalMart pricing and quality can be bettered any number of ways to shop.
The fact of the matter is, sometimes you need cheap crap, and no one sells more cheap crap than Walmart.
And if I can kill two birds with one stone and pick up the needed cheap crap and a few other things all at the same time, then i’ll brave the hordes of mouth breathers.
