The AbleGamers foundation has been added as a donation option on the IndieGala bundle site. IndieGala is a choose-your-own-price bundle site for independently developed games. You enter in what you would like to donate for the 12 games in the bundle, then you digitally download the games to your hard drive either DRM free or with Steam.
You can also choose who gets the money that you have donated. The money can go straight to the developers who made the games, a charity like Ablegamers.org, or the disaster relief fund for the Emilia Earthquake in Italy. You can even choose to give money to both by use of sliders to determine how much goes to whom. Visit indiegala.com or Ablegamers.org for more information.
