If you check this box, then the shopping cart will create a button that allows the customer to enter a coupon ID from the View Cart page.
To remove the coupon button from the View Cart page, simply uncheck this option.
Note: A valid coupon ID must exist before the customer can enter it. A coupon ID is created when you Create A New Coupon.
