While worrying about how to operate more efficiently, Amazon sells to outside companies the rights to use its operations and distribution centers. Amazon partners with Borders Books & Music and its borders division to provide borders with inventory, fulfillment of orders, and handling of its customer service. Amazon receives revenue from borders 's total sales and pays borders a commission. A Web site called "Borders associated with Amazon " was launched in August 2001, allowing Web site customers to access Amazon's listings, select books, music, videos and digital video discs, and it also Get information about the locations of Borders stores and the calendar of events at the stores. Borders ranked third in the online book market with 27 million USD sold last year, behind Amazon (1.7 billion USD) and barnsandnoble (320 million USD). The deal is more symbolic than money for Amazon, but it pleases Wall Street that was urging it to partner with a traditional "reinforced concrete" company. Amazon entered into a similar agreement with UK-based Circuit City bookstore Waterstones (which sells electronics), and the stores carry a variety of products.
