At Step 3: Payment Details of the checkout:
- Enter the Gift Certificate Code/Number in the ‘Enter Gift Card Number’ field
- Enter the pin number in the ’Enter Pin Number’ field
- Click ‘APPLY’ to redeem.
- Message appears underneath, “$XX has been discounted from your order".
As vouchers are classed as a payment term the amount of the voucher will not reduce the total value of your order.
However, once you submit the order you will be provided a breakdown of the voucher amount and what has been debited from your credit card (value of the order minus the voucher amount).
