Best non organic milk?

I hate to say this but.. I am one of the loons that bought in the organic milk is best epidemic. Lately, money has been more tight and we are on a budget. Which milk (that I can actually get at Kroger, Heb, Walmart, Randalls) type stores is the best. I am looking to buy a cheaper, non organic milk to save money. I noticed that Oak Farms says that they do not use any hormones or additives, and so do some others. My child drinks alot of milk and we want to keep costs down, once again.
