Proof of purchase in the context of "Premium (marketing)"

In marketing, premiums are promotional items — toys, collectables, souvenirs and household products — that are linked to a product, and often require proofs of purchase such as box tops or tokens 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.

Premiums predominantly fall into three categories, free premiums, self-liquidating premiums and in-or on-package premiums. Free premiums are sales promotions that involve the consumer purchasing a product in order to receive a free gift or reward. An example of this is the ‘buy a coffee and receive a free muffin’ campaign used by some coffee houses. Self-liquidating premiums are when a consumer is expected to pay a designated monetary value for a gift or item. New World's Little Shopper Campaign is an example of this: consumers were required to spend a minimum amount of money in order to receive a free collectible item. The in-or out-package premium is where small gifts are included with the package. The All Black collectors’ cards found in Sanitarium Weet Bix boxes are a good example of this.
