If the coupon code that you have entered is not working, please first check that the coupon code has been entered correctly.
Second, you should make sure that the coupon is still valid and has not gone past its expiry date.
Third, you should re-read the conditions to make sure that your order qualifies for the coupon discount. For example, some coupons are only set up to allow for one use per customer.
If the coupon code you are using is valid but you still cannot get it to work, contact our customer service representatives.
