For anyone unfamiliar with slickdealz, check out their forums for this sort of stuff. Specifically the
Free Magazines Forum.
Whenever anything like this pops up it will get posted. I was getting about 10 magazines a month I never paid for until I stopped reading them and they just stacked up(what the fuck am I gonna do with GIANT magazine?). Maxim/Blender etc are always popping up. Car & Driver and some other nice ones are there occasionally. And home magazines or fishing/other lifestyle type shit is always available.
