I found that Canadian Protein is way better. They have really good quality supplements, free shipping over $99 and I order there now. The milk chocolate whey tastes great and blows GNC out of the water! I order two at a time of the 5lb bags and there is no shipping. I haven't tried all the flavours, but the chocolate is great, Pb chocolate is good and I do mix them also. It's just so much cheaper though for better stuff that I have all but stopped GNC.
Shameless plug in the sense if you use this link I get some kind of reward or something something. I don't really track these things, but figured I should at least post it! I think people know me enough here though that they know I wouldn't recommend them if I didn't think they were good.
