anyone else ever hear of this?

Pretty sweet they do this. It's called humble bundle. Basically they bundle together a few games,  and you decide the price you want to pay. You also get to choose how to distribute the money since its for charity. You could be a dick and buy low for a couple games, or you could hit the average price and get all of them unlocked. My cousin paid me back with this because I bought him lunch today at work. Pretty sweet because you can link it to your steam account if you want.

I guess they come out with a different bundle every couple months or so. Check it out and help out a charity.
