To anyone out there who is a Mac user, you should check out MacHeist. I've bought it a few times, and always find at least a few applications that I use and/or enjoy each time. You can see the software bundle here: http://macheist.com/bundle/t/628417
If you use that link to purchase, I get more free software. You then get a link to refer friends, so feel free to post it here.
You can also get some free applications by completing "missions". That link is here: MacHeist » Missions
You can sign up for updates on their website. This year they did a cool thing where they had a few puzzle apps that gave you free software plus a discount on the bundle. In all honesty, Ill probably only ever use 1 or 2 of the software apps in the bundle, but they donate a significant portion of the sales to charity. I figured that was worth the purchase alone.
