Steam Games

I'm a college student without much spare money and I really want some steam games. I don't have a bank account and my paypal balance is currently $5.64. My only regular income comes from designing shirts on redbubble which is inconsistent and usually just over $20 (the minimum to be paid) per month if anything. So why not donate a few dollars to a fellow gamer in need? I'll get a lot of fun out of this to distract myself from soul crushing reality. I was going to make it for $7, which is how much I actually need for this game, but it wouldn't let me do anything less than $50. It would make my day if this were to actually come to anything.
