It's a CoSwap!

I was thinking of random things and this popped in my head. A CoSwap! what the heck is that you ask? It's coupon swapping!

So it's a little more in depth than it appears at first glance. What I mean by this is to have a collaboration among a few sellers(at least), maybe i'll start a twibe for it or something... What would happen is this, a group of sellers would swap "coupon" cards. I don't know about the rest of you, but i have little thank you cards that also have a 10% off coupon for their next purchase. So what would happen is each seller would send some of there coupon cards to each of the other sellers. When sellers are packing up sales they should include like 3 other coupon cards along with their own, rotating if need be so everyones card has a fair chance.

These coupon cards should be not so much an advertisement as an additional thank you, and no more than 3 because you don't want to bombard the customer. This would give sellers a chance get some more exposure as well as keep the customers coming back. Whether or not they use the coupons they are going to remember getting them, or maybe they will give them away to friends. I think this would be good for everyone involved. What do you think?
