Protein drinks

Really searching things right now..can some of you kinda tell me on average what you spend on protein drinks for a month?

I am Candian.

I but Whey Protien powder (choc) 2.2KG. 35 gr of protein and 2 carbs per serving and does 62 shakes. I only mix with skim milk. The powder is 39.99. It costs me more for the milk then it does the powder. I tried it with water but hated it.

Hope this helps!

I get my protein powder, body fortress, from walmart and I spend about $15 every 2 - 3 weeks.
