Yes! You're able to use your Gift Card to place an order online.
When placing your order, proceed to the payment screen and select 'pay with Gift Card'.
Simply enter in the long number from the back of your Gift Card, along with the security number and then select 'Validate Card'. The balance will then be deducted from your Gift Card and the order will be processed.
Paying part Gift Card and part card payment? Please remember to 'Validate Card' before continuing to enter your card details, as failing to do this may mean the whole payment is taken from your bank account.
Please make sure to keep hold of your Gift Card until you're sure you are keeping your items, as any refunds will be processed back to the original payment method.
