Nike gift cards are just like cash and can be used to make purchases on Nike.com, in the Nike App and at Nike-owned retail stores in selected countries. To use your gift card on Nike.com: Tick the box next to "Do you have a gift card, product voucher or promo code?" in the payment step of checkout. Enter your gift card number and PIN, then click "APPLY". You can find the card number and PIN on the back of a physical gift card or in the email for a digital gift card. The amount on your gift card will be deducted from your order total.
