If you are a Mac user, check out MacHeist. They are selling a bundle of Mac software worth over $200 for only $49, and $10 from every purchase goes to whatever charity you designate. As more money is raised, a few more apps will become available.
Personally, I was excited just because I was already considering Delicious Library and its part of this package. Props to the software developers for making their software available for a worthwhile cause.
The deal expires at the end of this week, so get while the getting is good.
