The folks at MacHeist are gearing up for another deal on a bundle of apps, but right now you can get a copy of Squeeze for free (regularly $9.95).

About Squeeze:

Squeeze is a background file compressor for Snow Leopard that transparently compresses the folders you configure it to process. Mac OS will read those files normally, they will just take less disk space.

So just head over to MacHeist to grab your copy now.
