I know that it has become popular for people to sell coupons for "free items" and stuff on E-bay, so I just wanted to put up this link to help you guys out in case you look at some coupons on E-bay that seem too good to be true. Word to the wise, if it seems too good to be true it usually is. This is a link to one of the "Coupon Fed" sites where they keep track of new counterfit coupons (it's quite a list). So, check it out sometime and just let your jaw drop at the amount of awards available for the arrest of the people who have created these fraudulant coupons and cost companies a LOT of money.

Hope you find it helpfull!
