Along with physical and digital products you can sell gift cards in your store. When enabled your customers can buy an electronic gift card for any range you specify and get it via email. Any order containing a gift card must have an order status of Paid before the gift card will send.
After a customer gets a notification email with the gift card details, they can forward this email to the gift recipient. The recipient can use the gift card to pay for products in your store till they spend the entire card balance or the card expires (whichever happens earlier).
