Abstract: Systems, methods, and non-transitory computer-readable storage media for joint use of gift codes and coupon codes. This technology can provide a way to use both a gift code and a coupon code in a same transaction, to discover corresponding codes for a given code, and to easily complete purchases using a gift code and a coupon code. The system identifies a companion code associated with a first value, wherein the companion code is at least one of a deal code, a discount code, and a coupon code. The system identifies a gift code associated with a second value, wherein the companion code, when used to make a purchase in combination with the gift code, provides a discount. The system offers the gift code for sale, and, upon a user purchasing the gift code, transmits the gift code to the user for combined use with the companion code.
