Yea, the amazon sellers flip between selling 4lb and 5lb tubs pretty routinely. Right now it's 5lbs for $42, last time I bought was 4lbs for $38. $42 is obviously an even better deal. However I can't see the supposed BCAA content. It just says "protein that contains a complete amino acid profile of all 9 essential amino acids" which could be total bullshit.
