There are some possible reasons why...
The voucher can only be used on the UK website (excluding mobile version).
Following an unsuccessful order on the website, the voucher is deactivated for 2 hours for security. It is not possible to pay for an order with the voucher during this time. Return in 2 hours to complete your order!
On the website, you can not use more than 5 vouchers for the same order and/or for an amount exceeding £ 3,000. Furthermore, a gift voucher can not be combined with a credit note.
If the gift voucher balance does not cover the total amount of the order, the payment of the difference by debit or credit card can not be less than £1.
If, despite all these checks, you still can not use your voucher, send a request to Customer Service below.
