You can take additional surveys every week or so and the subscriptions stack, so you can do two CA subscriptions and you won't get two issues. I've been doing this for a couple years, 100% legit. Given away a couple of CA subscriptions too for the hell of it. Also sometimes they have some other good magazines; I've seen Playboy, Wired, Maxim, Mens Fitness. You just need to check back to see what they've added.
