Premiums are promotional items—toys, collectables, souvenirs and household products—that are linked to a product, and often require box tops, tokens or proofs of purchase to acquire. The consumer generally has to pay at least the shipping and handling costs to receive the premium. Premiums are sometimes referred to as prizes, although historically the word "prize" has been used to denote (as opposed to a premium) an item that is packaged with the product (or available from the retailer at the time of purchase) and requires no additional payment over the cost of the product.
