For protein powder drinks, you can get Pure Protein 100% Whey for $17.00 for a large, large jug at Walmart. One scoop with 1 cup skim milk, 1 splenda and a handful of ice blended in your blender make a nice, chocolately shake that tastes great at about half the price of the isopure. However, I too really enjoy the Isopure clear protein drinks in the bottle, especially grape. I drink at least 1/2 a 20 oz bottle daily to boost my protein intake (I am just 16 days out from surgery). They are expensive but you can shop around.
