I buy Premier Protein from Costco. They are 30g of protein, 160 calories, 1 g sugar, 11 oz disposable container (like a juice box). I like chocolate, the vanilla tastes a little funny. But if you heat up the vanilla and mix with a shot or two of espresso it's almost like a latte! They cost $24.99 per box of 18 here in Washington. I think they taste better than Slim Fast or the Atkins brand protein shakes, and they have a ton of protein.
