I'm interested in this as well. They're not usually cheap.
As for the flavors, I think they're all made with WPI, which should be fine if you're lactose intolerant (I am), so look up the ingredients.

Amazon with prime; best price I have seen.
Iso new flavors as well. Have the cookie dough ones which are pretty good.
I don't personally have prime. Do you use the US website?
