Sorry, but I just don't buy the "Mom and Pop stores being pushed out of business by Walmart" line. The Mom and Pop store as a source for basic necessities has been extinct in most locales for over thirty years. They were driven out of business by grocery supermarkets like Albertsons and Safeway, mall anchor stores like Penneys and Dillards, discount stores like K-Mart and Target, and pharmacy chains like Walgreens and CVS. It's those stores whose customers Walmart is drawing away, not Mom and Pop. Moms and Pops are running gourmet shops, designer boutiques, consignment stores and the like and Walmart is taking 0% of their business away.

If you want to talk about Mom and Pop stores being driven out of business, don't look at Walmart. Look at the big "home center" stores like Home Depot and Lowe's. Every time one of them goes in, several independent hardware stores and lumberyards in the area go under.
