I’ve been doing this for a couple years, but if you haven’t heard of MacHeist, you should definitely sign up and start checking it out. Here’s the link: MacHeist Signup!
Basically how it works is you sign up (which, did I mention, is free), then you get to do some sick online missions that lead to registration info for free copies of premium Mac software. Last year, I finished about 2/3rd’s of the missions, and I got over $150 worth of free software! Plus, at the end, you have the option to buy the yearly software bundle, which is a $400+ value for around $50.
Overall, one of the coolest (if not the coolest) ways to get mac software for free online.
PS. Check my twitter (http://twitter.com/thinklime which should also be in my lifestream) if you want the coordinates for the first copy of free software (Daisy Disk, a sick hard drive space management tool).
