Third-party vendors can sell their goods to Amazon customers on the Amazon Marketplace. The marketplace offers a number of product categories and gives vendors the ability to control their listings, ship orders, and provide customer care. The Marketplace offers customers the same purchasing options as Amazon itself, with the extra benefit of possibly discovering rare or niche goods. Customers should use caution and due diligence before making a purchase from a third-party vendor, however, as not all Marketplace merchants are created equal.
