Amazon just cancelled the Subscribe and Save option on Optimum Nutrition Gold Standard and I am getting low at home. Are there any better options for under $50 for 5 lbs? I noticed that they have the S&S service for Muscle Milk, anybody have an opinion on that one way or the other compared to Gold Standard? If it makes a difference I only drink a protein shake after lifting, 1 scoop only, mixing with Skim Milk. I'm not looking for meal replacement or anything like that.
