Value Mags is one of my favorite places to get FREE magazines. I do not recommend signing up for magazine trials but these are not trials. Value Mags offers FREE magazines, no strings attached. You'll never receive a bill. I have received several magazines from them.
Worried about what to do with all of the free magazines once you've read them? Here is a list of just a few places I like to donate mine: public library, my child's school, my gym, doctors' offices, use them for craft projects, etc.
Seventeen Magazine (3 free issues)
Family Circle (2 free issues)
