i went in on a similar deal with them...got a "free" radio with a $1 shipping charge. The radio sucked, and wasn't worth the $1. The quality was so low, it was something i could pick up at a $.99 store. Also, you have to remember to call and cancel before the alloted time, else they're gonna charge you. It's pretty easy to cancel, but they'll ask you why you want to cancel. I just said i wanted the freebie. they then asked me, ok what's the real reason, and i repeated myself. i dunno if they believe me, but they did cancel my membership.
Honestly, I don't think it's worth it...the product is cheap and inferior (at least the radio that i got was). If you do decide to join, be sure to cancel before 30 days.
