[Request] Dungeon Defenders on Steam

I've never posted here so I don't exactly know how it works, but I really want this game. I'm only 13 so I can't exactly buy this game for myself and I don't want to ask my parents just because I don't want to seem spoiled or anything. At the moment it is $3.74. If someone buys it for me, I would be really happy :) I will also make you any terribly drawn picture of your choice in MS Paint ;P Thank you!
