Humble Bundle lets you pay what you want for some great stuff and then you get to decide how the money gets split up. You can split the bundle between the developers, charity, and Humble Bundle themselves. I usually do a 3 way split whenever I donate to keep it fair.

Finally, if you pay $20 or more, you will unlock Bioshock Infinite and XCom: Enemy Unknown
