Consumer-to-consumer

Consumer-to-consumer (C2C) (or citizen-to-citizen) electronic commerce involves the electronically-facilitated transactions between consumers through some third party. A common example is theonline auction, in which a consumer posts an item for sale and other consumers bid to purchase it; the third party generally charges a flat fee or commission. The sites are only intermediaries, just there to match consumers. They do not have to check quality of the products being offered.

Consumer-to-consumer (C2C) marketing is the creation of a product or service with the specific promotional strategy being for consumers to share that product or service with others as brandadvocates based on the value of the product. The investment into concepting and developing a top of the line product or service that consumers are actively looking for is equatable to a Business-to-consumer (B2C) pre launch product awareness marketing spend.
