I can get it at my local supermarket.
I tried it, primarily because my wife is a big fan of whole wheat. It made an ok pizza, but compared with traditional high-gluten flour, it wasn't that good. She liked it. You might find that it's great. As for me, I'm a purist. My philosophy is that if you're going to eat healthy, don't eat pizza. I'd rather eat perfect pizza less often, rather than "healthy" pizza that I don't like more often.
Mixing it half & half with regular flour DID help substantially.
