You can apply your Gift Card to your shopping bag online (which you can access by clicking the bag icon at the top right of your screen).
Enter your Gift Card code, and click Apply.
Once successfully added, you will receive a confirmation on your screen.
You only need to apply this once. The value will be held online until you checkout so you can continue shopping and then move to the checkout, without needing to re-add your Gift Card code.
Please note: If your Gift Card was purchased prior to 22nd March 2021 you will need to contact our Customer Service Team at email@example.com
