If a customer wants to buy a gift card for someone else, then they need to forward the gift card email to the recipient.
When making a purchase, a customer can redeem the value of a gift card by entering its unique code at checkout. This code isn't case sensitive. A gift card holds a balance, which can be spent over more than one order. Gift card balances are applied to the total value of an order, which can include shipping.
When a customer redeems a gift card, the checkout displays one of the following options:
If the balance available on the gift card is greater than or equal to the order total, then the customer can click Complete order.
If the balance available on the gift card is less than the order total, then the customer is prompted to choose a second payment method for the balance before placing the order.
