Although I am not a fan of Wal-Mart, this is one of the better ones I have shopped. The store layout is much more logical than many in other towns. It is also very convenient to have the food center if you only need an item or two. In contrast, the items are nearly as fresh or as high quality as those from the chain grocery stores. I would still shop there if I had a long list.
Because it is 24 hours you will often find tons of teenagers wandering around looking for entertainment in the middle of the night, but this is the best time to shop to avoid inconsiderate people.
