Pop photography still my all time favorite magazine and my friend just told me how he got a free subscription. He got some business cards from vistaprint.com (free + shipping) and at the end of the offer he was given a choice of magazines with a one year subscription... FREE. I guess the magazines just want to hook you for a year and then get your money after that.
