The Problem - 21.7% of US daily deal coupons are never redeemed. It is the industry's untold secret.
The challenge is to persuade buyers of unwanted coupons to make an effort to sell them.
The Solution - A secondary market in which coupons are directly bought off sellers for credit and sold to buyers for cash (or redeemed credit). By far the simplest solution for sellers, who pose the greatest entrance barrier to this highly profitable market.
