First, be sure you have entered the entire 16-digit card number and 4-digit pin accurately.
Next, click on "add". A prompt will tell you the balance on your gift card.
Then, click "apply". The gift card balance should now be applied to the order. If the gift card does not cover the remainder of the order, you will now need to add an additional form of payment to complete the order.
If you are unable to apply your gift card after following the steps above, please contact our customer service department and we will be happy to assist you in placing your order with a Tillys gift card or eGift Card.
