If you use a Mac, you absolutely must check out the insane deal that MacHeist -- an alliance of independent Mac software developers -- is offering. For $49.95, MacHeist is selling $428 worth of fully-featured (i.e., not demo mode) Mac software. And to make the offer that much sweeter, a good chunk of the proceeds go to charity. As of this writing, $227,000+ has been raised so far.
Plus, the software is good. I would recommend all three of the twelve titles that I've previously used:
SnapzProX - a screencapture utility that's GREAT for creating screencasts iStopMotion - a great program for shooting stop motion animation 1Password - a browser extension that saves all your passwords in one place, and generates secure passwords
I'm an especially big fan of SnapzProX. Last fall I used it (in demo mode) to create a screencast for some of my students. I found it to be the best application of its kind on the Mac. It normally sells for $69, but for the next four days people can get it, plus 11 other applications, for $20 less. And it goes to charity. So I'm getting out my credit card now.
As for the charities represented, according to the MacHeist wiki:
Purchasers can choose from the following list of ten charities, or opt to split the donation from their purchase evenly among the choices.
* Action Against Hunger * AIDS Research Alliance * Alliance for Climate Protection * Direct Relief International * Humane Society International * The Nature Conservancy * Save the Children * Save Darfur * Prevent Cancer Foundation * World Wildlife Fund
