Enter your 16 digit gift card number and your PIN at the checkout page under 'Use a Gift Card'. You can find your PIN on the back of your gift card under a scratch-off silver panel.
The website will first request you to 'Check Balance' and then ask you to click again to 'Apply Funds'. Please ensure you follow both steps to use the gift card successfully. Any remaining balance after a gift card balance has been applied, can be paid via credit/debit card, PayPal or New Look Store Card.
