I agree about the Wal-mart "organics" not always being the best.
But this depends largely on your particular store. Some WM's are much better than others, in what they carry and also the quality of their produce department.
So, I would suggest just stopping in one day and checking it out.
I'm not much of a H*llmart shopper, personally, but depending on where you live, it may be your only option.
I do about 95% of my shopping at Kroger (waaay better produce depart.) and alot more variety as well, 3% at Bi-Lo and the other 2% at Wal-mart.
But I will say, that Wal-mart in this area is THE only place that sells tofu, if you can believe that?
I sooo miss living in Florida, you could find veggie/vegan options at ALL the grocery stores.
