Please wait to use the voucher code until you are certain that you are prepared to place and pay for your order because once you do, it cannot be used again. The most frequent causes of promotional codes not working are: being out of date; being used on ineligible items; or the order threshold not being met. If you're still having issues, you may get in touch with them by filling out their fast form, and they will be pleased to walk you through the process of redeeming your discount online.
