We have one of the UK's biggest WalMarts about half a mile from the house, and it is where we tend to go when we just need to grab something quickly, because it is easiest to get parked, get in and out of. There are closer supermarkets, but they are a pain in the neck.

Morally, I don't like WalMart, but they do have better food and goods than the others here, although to be fair, I can get way better food about 12 miles away, at the weekend farmer's market - just is a lot of time and effort:-)
