Canadian here with another question. so I think I will take the plunge and purchase Quest powders from Amazon. What I am wondering is, since there is such a significant variation in availability. what is the actual size of the container? I realize we pay more here but does $57 for 1. 6 lbs seem right? I am always cautious when ordering consumables from Amazon because I have heard some stories of the products not being what is labelled. ughh Thanks
