Nike has confirmed that their products will no longer be sold on Amazon so they can focus on selling directly to their customers. Two years ago, a partnership between the two companies was formed under the agreement that Amazon would refuse to sell products from unauthorized third-party sellers. Neither company has commented on if their partnership was successful and profitable, but both companies are seeking to build their customer base and consider other partnerships. Early reports, however, indicate that Nike and Amazon were unable to keep up with counterfeit sellers on the website.
