The present invention extends to methods, systems, and computer program products for delivering customer specified receipt types at checkout. A customer specifies receipt delivery preferences at a mobile device (e.g., specifying delivery of a digital receipt and/or a paper receipt at checkout). The mobile device sends the customer's receipt delivery preferences to a receipt preferences database server for storage in a receipt preferences database. During a sales transaction, a point-of-sale (“POS”) system refers to the receipt preferences database (or a relevant portion thereof) to access the customer's receipt delivery preferences. Based on the customer's receipt delivery preferences, the point-of-sale (“POS”) system delivers appropriate types of receipts (e.g. digital and/or paper) to the customer.
