We go to both Wal-mart and Target, depending on our other destinations (Mecklenburg library is near the Target :-). Target has been "gentrifying," and it's harder to find really cheap stuff, like $2 shower curtains and tableclothes, there. But for boys' clothes, it's better than Target.
Do you have an Atwood's farm store near you? We go to the one in Vinita, about 30 minutes from us. They have everything except kids shoes. I have bought jeans for the boys for less than $6. They have triple boxes of jigsaw puzzles for $5, 3 pound cans of coffee for $3 and pratically giveaway prices (35 cents) on packages of seeds.
Give it up with their website, though. It is terrible and has zero information.
Gotta love that $2.00 shower curtain and tablecloth. Neither last long enough to mildew or wash. Dang, don't even have to buy wash soap. Al
