I buy four gallons of Horizon ultra-pastuerized organic milk at Sam's at a time. (I have to drive 30 miles to Sam's.) I have a 6'2" 16 year old boy in the house who drinks a lot of milk. Gallons and gallons of milk. I switched him to organic when he started drinking so much--if he's going to drink so much I want it to be good for him.

I can buy the Horizon in such quantities only because the expiry date is about 6 weeks out when we buy it. It rarely lasts more than 8-10 days, but on occasion he has fallen behind, and the milk has never been less than perfect.

It's always refrigerated, at Sam's and at home.
