Humble Indie Bundle 2

Link

It's a bundle of 5 indie games (this time, they have Braid, Cortex Command, Machinarium, Osmos and Revenge of the Titans), all of which are good games and drm free (they all work on mac, pc and linux). You pay what you want for the bundle, and choose where your money goes (to the devs of the games, to 2 different charities (Electronic Frontier Foundation, or the Child's Play Charity), or to the people organizing it(you set how much you want to pay, then choose how much goes to each)). You can't directly pay for it with a credit card, but have to use Paypal, Amazon Payments, or Google Checkout.
