Build a Bundle, pay what you want, donate to charity!
It seems like there is an indie bundle every other day, but this one has a unique feature. The bundle consists of 12 indie games, and you must choose a minimum of 3. The minimum payment is $3 and will increase as you select more games, however you can also pay much more if you wish.
The bundle also has a nice bonus to it. It has set up a number of goals, which when achieved grant you access to bonus materials, such as soundtracks and DLCs. To purchase the bundle you must do a brief sign up if you are not a member already, don't worry though, it is incredibly quick and does not make you activate via email.
