Have you read All You magazine? It's a great magazine that always has tons of coupons in it. Not only is it great for all the coupons, they actually have some good articles and recipes in it so I really enjoy reading it before I cut out all the Q's! The only place I know that you can purchase the magazine is in Wal-Mart for 1.97, but if you subscribe you can get it for less than that an issue.
Right now they are offering a promotion and for every two people that sign up under me they will add an extra issue to my subscription. So if you think you would be interested in subscribing add your name and email to this link and they will email you their subscription offer.
