The discount code does not update the total cost within the cart on this page. Please proceed to the next page and enter the discount code in the checkout window (Black Box). After applying the coupon on the next page, you will scroll down to see the discount is applied. We are working to resolve this issue. Please be assured, the discount code does work. However, it will only work when entered in the checkout window (proceed to the next page). Thank you for your understanding.
