This article will show you how you can use more than one of a client's Gift Card/Voucher for payment in a sale.
When you're on the Purchase screen and ready to process the payment, click the Gift Card/Voucher option as the payment method and add one of the client's gift cards/vouchers to the sale
To use another gift card/voucher in the same sale, click the dropdown arrow that appears beside the Gift Card/Voucher option (this only appears after you have already added at least one gift card/voucher to the sale), then click New to repeat the same process as before and add another gift card/voucher.
