Consider that if K-Mart goes out of business, I can guarantee that Wal-Mart will raise their prices. Wal-Mart kills their suppliers and has terrible service (if you don't believe me, look at the checkout lines). I agree that K-Mart needs to clean up their stores, but they have 10x better sales than Wally-World, and Target is trying to get too hip.
If you want variety in your stores, and low prices, patronize these guys. If you don't believe me in service, read the latest Consumer Reports, which rates grocery stores. Super Wal-Mart rated low in service, but high in price. I won't buy any more food at the one in Gilbert, AZ until they clean it up.
