The first P.
The marketing mix is the complete offer a seller makes to any potential buyer. In classical marketing theory it is composed of four parts: the product, its price, channels of distribution (colloquially called place in order to have a term beginning with the letter P), and promotion which includes incentives, public relations, and advertising. These are the four P's which every MBA student must master.
