This can be a pretty good deal. For example, a 2-Year Redbook Magazine Subscription is $10 and is eligible for the $5 bonus, so it ends up being $2.50 a year. Another bargain is the 2-Year All You Magazine Subscription for$34, which is eligible for the $10 bonus, making it $12 a year. (Have I told you that I love All You Magazine? It's full of coupons and money saving ideas.)
