I was in Arnold today so I stopped in that Dierbergs. They seemed to carry only buttermilk and skim milk from that brand, and they had no skim milk in stock. I didn't have time to go anywhere else. I may just have to make a special trip to WFM once a month and buy in bulk, especially if it really is less expensive... supposing unhomogenized milk behaves well after being frozen? I've never actually frozen milk before.
This is a great excuse to go to WFM! DH doesn't know what's coming. I buy Earth Balance at the health food store but I'm betting it's less expensive at WFM as well.
