A great example of what a C2C model is would be eBay, an online auction site, and Amazon, a marketplace that acts as both a B2B and C2C solution. Consumer-to-consumer eCommerce (sometimes known as customer-to-customer) enables the building of relationships between end-users, where the website acts as a platform where consumer correspondence occurs. Other business models also conduct business to sell goods to different types of potential buyers, including business-to-business (B2B) and business-to-consumer business models (B2C).
