Cookie stuffing is something different; that usually refers to outright trickery like embedding affiliate links in images or malware. This is just affiliates taking advantage of the fact that if you put a coupon code box on a checkout form, people will search for coupons right before checking out. Run a coupon site, put a "click here to activate coupon" link on it, and suddenly you're being paid for sales the merchant was already going to get.
