Heh...I'm way too disorganized to do milk bottle trade-in. But I do think I've seen milk in glass bottles. Might not have been there, though. For one thing, there's a place back home that sells raw milk in bottles - cream, too. Or did, anyway.
I think I've seen Helios brand stuff. I'll check it out! If they have both brands, is one better than the other?
I've had the Helios...it was ok...try the Lifeway.
