I've been struggling with this also and feel that people who don't have a coupon might abondon their cart. We currently suggest signing up for our newsletter if they're interested in recieving coupons and place a link next to the coupon box. I'd just as soon get rid of the box altogether. Question is, if you don't offer coupons, how do you offer incentives? Basic sales propmotions? An online coupon that anyone can use at check-out? What's the alternative?
