Protein shakes

Personally I have used mostly Body fortress sold at Wally world... lol It does the job for me and I can afford it. I can't afford all the higher priced protein mixes along with all the supplements I have to take too, So it has been  okay for me though I don't mind trying other's just can't afford them is all so wally mart has it ranging at times from 12.98 to 15.98 for a 2lb container they have vanilla & chocolate. I have bought both and both are good. I prefer the chocolate though. The Vanilla is good for when you want to add other stuff to it to flavor it. Does anyone have a low cost favorite mix they can share  about?
