Why don't they sell milkshakes in gallon jugs? They sell yogurt that you drink, smoothie drinks, etc. Why not milkshakes? I would love to keep a gallon of low-fat, skim-milk milkshake in my fridge at work. High-protein energy for a man who loves milkshakes. That could be the slogan! Why doesn't this already exist?
