$318 for 30lbs of WPI. The good stuff.

About 170-175lbs
Protein intake varies from 100-150g daily.
I find WPI to be the most time-effective and macronutrient dense protein source for me. This allows me to get about 10-15 servings of produce daily. I don't do nearly the mileage that some of you do, so I work to keep my caloric intake weight-neutral. Works for me.
Are you a vegetarian?
It is very convenient although I sometimes feel like I am getting gipped by the lack of mastication.
