Humble Indie Bundle 3, which already allows you to act with severe frugality, now throws in Humble Indie Bundle 2 when you pay more than the average price ($4.97 at time of publishing), or if you already bought it before 10:30AM PST this morning.
It seems the new metric for measuring interest is "Meh, I'll wait until there's another bundle in it."
This latest mutation contains, in addition to six cool indie games (like Crayon Physics Deluxe, And Yet it Moves and VVVVVV), the full Bundle 2 set: Braid, Cortex Command, Machinarium, Osmos and Revenge of the Titans.
Well, maybe it's not quite the full Humble Indie Bundle 2 as it was. It was later expanded to include ... Humble Indie Bundle 1. Think of that as a warning: At some point, your penny pinching and love for recursion will intersect inside one of these bundles.
