I've heard these mags get ripped apart on this site for a long time and don't think that it is totally justified.
There is a lot of useful information (specifically from accomplished bodybuilders themselves) that can be very beneficial to beginners who are clueless and have no one to show them the ropes.
True, there is alot of b.s. programs and advertisements, but even as a newbie I could see through it all.
The most helpful information I received was the articles on nutrition - something most beginners know nothing about or neglect all together. I don't subscribe to them anymore because most of the info seems to be recycled after a while but still will pick one up once in a while for motivation.
I had the same problem with the delivery process though where I didn't receive a mag for a few months and then receive three all within a week.
