The third annual Humble Indie Bundle is currently available for purchase, and while it already includes six pretty awesome games, if you buy the bundle for even one cent more than the average price at the moment (currently $5.16), you'll get the games included in the 2nd Humble Indie Bundle! Braid, Cortex Command, Machinarium, Osmos, Revenge of the Titans are the five games from the Humble Indie Bundle 2, and seeing as how most of those are actually better than the games in the Humble Indie Bundle 3, you'll be getting a truly stupendous collection of awesome titles for less than the price of a burger at In-n-Out, or Hardees, or White Castle, or whatever the hell constitutes a "top tier" fast food restaurant in your area.
You can buy the bundle at the official site, here: Humble Indie Bundle 3.
