protein shake any advise pls
 

hi all
i was in holland and barratt today buying some atkins products and came across instant milk and egg protein strawberry shake mix aimed at body builders each serving has only 1.1g of carbs, its a big tin and at a guess you would get 30 servings it cost £4.49 and dont taste to bad ether my single seving of atkins shake cost me £1.89 big differance but
i feel it cant be that simple is there somthing hidden that i dont know about it seems to good to be true. any advice pls

Has nobody come across these shakes
