The gift card code must be sent to the email address specified during checkout, but only and exclusively after the order has been completed.
Administrators can always recover the codes of the gift cards at any time from the related order detail pages.
Users can use their gift cards whenever they want, adding the code in the “Coupons” sections of the “Cart” or “Checkout” pages. Coupon code has the same value of the gift card amount they purchased, but it’s not essential to use it in a single order. Indeed, if the gift card value doesn’t cover the order amount, its remaining balance can be used on other purchases.
