I'm curious as to fellow Canadians finding deals on protein. I get mine at costco, but it tastes like ass (only comes in vanilla), but it mixes well and is high quality stuff. It works out to about $10 canadian a pound, which is a little above what I paid per pound (after shipping), for some Optimum whey supreme which doesn't mix well and has only 21g/serving as opposed to 32.
Oh and about favorite, well I liked Iso XP chocolate alot. I had some laying around at home when I went back for christmas, I bought it a good while back from the local GNC (ugh!, although it actually was a decent price). Tasted like a chocolate-vanilla milkshake even in water.
