Amazon employs a multi-level e-commerce strategy. Amazon started by focusing on business-to-consumer relationships between itself and its customers and business-to-business relationships between itself and its suppliers and then moved to facilitate customer-to-customer with the Amazon marketplace which acts as an intermediary to facilitate transactions. The company lets anyone sell nearly anything using its platform. In addition to an affiliate program that lets anyone post-Amazon links and earn a commission on click-through sales, there is now a program which lets those affiliates build entire websites based on Amazon's platform.
