I do my best to avoid Wal-marts and their ensuing crowds of freaks but when money is tight and or I don't need fresh meat/fruit or vegetables I do like to come here as they do offer some cheap(less expensive) products. The trick is to make a list; but on a pair of blinders and don't look around inside the store. (I always fall victim to the DVD bins)
You want to make a budget, a list and as long as you stay to the list you will leave with some coin in your pocket.
