How do products deliver packages of tangible and intangible benefits?

"Consumers are really buying packages of benefits that deliver value, which always includes some tangible aspects and some intangible aspects. The person who buys a plane ride on United Airlines is looking for a quick way to get from one city to another (the benefit). Providing this benefit requires a tangible part of the product (a plane) and an intangible part of the product (ticketing, maintenance, and piloting services). A person who purchases accounting services buys the benefit of having taxes completed on the correct tax form (tangible part of the service) and having the taxes prepared correctly by a trusted person (intangible part of the service). Marketers must know how consumers view the types of products their companies sell so that they can design the marketing mix to appeal to the selected target market."
