Ever heard of a coupon train? Well, I'm addicted to them. A coupon train is a envelope mailed to each rider full of coupons! Sometimes you hit gold in these things! I've participated in a few, and these go all over the United States, so you collect coupons that your local Sunday paper may not offer to you. Simpley amazing! Often, you post what you need, and what you dont need, and the others help you out, and you do the same for them. :)
