Digital Gift Cards are delivered by email which contain instructions to redeem them at checkout. There's two ways to order:
1) Add the desired gift card amount to checkout, order and receive the email yourself, then forward the gift card email directly to the lucky recipient or download and print it to give in person.
2) Select "I want to send this as a Gift" then complete the form to send the gift card to the recipient's email address directly. Add to cart then checkout as normal.
