I wish I could afford organic! I just follow the old adage that "if you don't eat the peel, you don't need to buy organic." For the things with peels that we eat, I just wash it well, and hope for the best.
I was buying organic milk for a while (I was concerned about the hormones) until I noticed that all of the milk at the store had a disclaimer on the label saying that the cows had not been fed hormones, and the milk was "hormone-free". As for the meat....well, again, I just hope for the best. My kids aren't really bg meat eaters, and my husband and I could probably lay off it, as well.
