E-commerce transactions generally fall into one of four business models: B2B, where businesses exchange products, services, or information between businesses; B2C, where businesses such as Amazon.com or Lands End.com sell to consumers; C2B, where consumers can bond together and buy in volume at the lowest prices; and lastly, C2C, where consumers buy from other consumers — typically from online auction or classified ad websites such as eBay.
