Apple is offering .Mac members a free copy of Aladdin System's DropStuff, which usually costs $30.

DropStuff is used to compress files for storage and email-attachment use, and for online file downloads.

The free download is available to .Mac members until April 13.

Aladdin is also offering .Mac members a $40 discount on the full version of its compression utility suite, StuffIt Deluxe. This costs $39.99 and is also available until April 13.

This is a suite of compression tools capable of creating .Zip and TAR compressed files. It searches, browses and edits archived files without unstuffing them. It also includes Secure Delete, a digital document shredder.
