My favorite variety of Fage is the 2%...I'm afraid to try the full fat version because I'm afraid I'll like it even better and it's too high in fat, lol.
I've bought the Oikos brand at Super Walmart before, but they only have it in 0% which isn't as yummy. It's okay in a pinch though.
Like someone above said, email the company. I was able to find it at some other places however. I live in Pennsylvania, and I can get it at Trader Joes, Whole Foods, Giant Eagle, and my local health food store. Sometimes it is NOT the regular yogurt section. At my Giant Eagle for example, it is by the dairy section in the organic food section.
