What is Consumer to Consumer (C2C)?

Consumer to consumer (C2C) is a business model that involves the sharing or sale of products and services between consumers. The C2C model is often facilitated by a third-party service provider or company and is usually conducted on the internet. Examples of C2C platforms include online auction platforms (e.g., eBay), exchange of goods and services platforms (e.g., Craigslist), and digital payment platforms (e.g., PayPal and Venmo). Amazon's online marketplace also operates using both a business to consumer (B2C) and C2C model. C2C is one of four main business models alongside B2C, business to business (B2B), and consumer to business (C2B).
