Coupon Trading

We all have coupons that we'll use and coupons that we'll never use in our lifetime. I'd like to create some sort of "coupon trading" arrangement. In this post, if you come across a coupon that you would like more of, put it out there and see if anyone might be willing to trade with you. It's up to you guys to make this successful! Try to be fair and if I need to step in, I'd be more than happy to.
