If your not familiar with MacHeist, it is an annual software sale involving some awesome applications by indepedent devleopers. Basically, they bundle the software to get some hype, and MacHeist donates a portion of your purchase to a charity of your choice. If your a Mac user, this is a can’t miss for 50 bucks.
They always have some awesome apps (last year I picked up TextMate and Delicious Library), and this year is no exception. I’ll let you check out the site for more info. (Disclosure: my links are referall links, if I pass along a sale or two MacHeist will throw in two more bonus apps.)
