***** Usage ***** .. _Selling gift cards: Selling gift cards ================== A gift card `Product <concept-product>` can sold on a `Sale <sale:model-sale.sale>`. When it is a service, the `Gift Card <model-sale.gift_card>` are created and sent automatically by email to the email address from the sale line or, if this has not been filled in, to the customer's email address. When the *Product* is goods, the *Gift Cards* must be linked to the outgoing `Stock Moves <model-stock.move>` that send the gift card to the customer. .. _Redeeming gift card: Redeeming gift card =================== Existing `Gift Cards <model-sale.gift_card>` can be added once to a `Sale <sale:model-sale.sale>`. On quotation, a return line for the amount of each gift card is created. .. note:: If the value of the redeemed gift cards exceeds the value of the sale then the sales total will be negative. This will normally result in a credit note being generated by the sale instead of an `Invoice <account_invoice:model-account.invoice>`.
