I haven't ordered from them. I have ordered from www.netrition.com before. They had a flat rate delivery fee which I liked. The only reason I don't order from them now is we got a vitamin cottage that carries a lot of the stuff I used to have to get on line.
I don't personally know of anyone in my family with celiac disease, but my wife and I choose to stock up on rice rather than wheat to preclude any problems with gluten down the road. We haven't yet had a chance to do any baking, but I've found a few recipes for rice bread that I want to try sometime soon.
