Attack Magazine has coordinated with several vendors to offer free sample packs. The most recent release is from CNTRL Samples. This pack is made of some of the tracks from recent releases from the company. If you produce any kind of electronic music, some free samples never hurt to keep around. There are also sample packs from several other studios to check out.
