Hopefully if enough of us buy them they will not chose to discontinue them. I've been buying them now for a few months, and although not my main protein shake (I do BSN most days) I like their convenience when I'm pushed for time.
I am extremely picky about taste and have tried several different protein shakes and can't drink them. If I was to buy the ones your are talking about at costco and tried one and didn't like it would they let me return the rest?
I have not tried either freezing or heating though I do drink them at room temp. They use to say do not freeze but looking at the new packaging I do not see that warning any more. Almost 4 years out and I still drink them every morning.
