A coupon code box is the box placed on a checkout page wherein consumers have to enter a coupon code to have a price cut.
Use of coupon codes is a matter of debate. Indeed, coupons are often essential for e-retail sites but the presence of a code box on the checkout page may hurt conversions and margins when the consumer sees the box and had not forecast to use one coupon.
Coupon box use can be optimized. For instance, the box can be pre-populated for visitors incoming from best known coupon sites. The box can also be automatically hidden when there is no coupon according to the nature or value of the order.
Use of coupon box deserves tests.
