A system and method for a supplier to offer multiple new products to a first person and multiple pre-owned products to a second person are disclosed. The invention includes a method wherein the supplier receives a request from the first person for a first new product. After accepting the first new product, the supplier stores data identifying the first person and data relating to the first new product in a memory of a computer. Thereafter, the second person queries the supplier about a pre-owned product. The supplier searches the memory of the computer to determine whether the data relating to the first new product satisfies the second person's inquiry for the pre-owned product. If so, the supplier transmits an offer for a second new product to the first person based on the data identifying the first person. If the offer is acceptable to the first person, the supplier provides the second new product to the first person and the pre-owned product to the second person.
