Tying (informally, product tying) is the practice of selling one product or service as a mandatory addition to the purchase of a different product or service. In legal terms, a tying sale makes the sale of one good (the tying good) to the de facto customer (or de jure customer) conditional on the purchase of a second distinctive good (the tied good).
