are you sure you wanna buy whey?
After surfing around the iron addicts forum (great forum, IA is extremely knowledgeable), IA has stated that whey is pretty much useless except PWO and even then isn't exactly necessary.
You're better off with a mix of whey, egg, casein to slow down the absorption rate. that way you can use it effectively at ANY time of the day and it won't go to waste.
something like this I found was recommended
