OK so it the worst MacHeist I have ever seen but it is free this time, each app is the full licensed version, there are no catches and if they get 500,000 participants Marina Write gets unlocked as well.
For those that don't know MacHeist periodically put a package of apps together for a heavily discounted price, they are usually great packages, this one is average in comparison but it is free.
It will only be up for a week so if you have a Mac get it now.
Just a heads up, apparently the servers are struggling already with serial number requests and some have reported apps not working, hopefully it will be sorted quickly. Some users have said that after you get your serial it is better to download the app from the official site.
