Thanks very much for the info on the "Where is my milk from" website!
We have been playing with the code-finder and we have been very intrigued to see that some big house-brands of milk are from the same plants as Dean's milk. Jewel-brand milk, WalMart's Great Value milk and Sam's Club Daily Chef milk all track back to Dean's plants in either Huntley or Harvard IL.
To me this says why pay more than $4 a gallon for Dean's at these stores when a gallon of the house brand is from the same plant and is as low as $2 plus change? I have a hard time imagining that they run two different streams of milk through these plants.
I put a shortcut to the code-finder on my smart phone and intend to try it on other dairy. --Joy
