Sales grew for the high-end warehouse club, and Costco members continue to demonstrate a strong attachment to the brand. Stores in North America, the U.K., Korea, Taiwan, Japan and Australia succeed by carrying a narrow selection of luxury goods at competitive prices. Known for its corporate responsibility, Costco is moving to raise awareness for its pharmacies, and for its North American website, which it plans to expand into other countries. New mobile applications will also help Costco grow and improve in search rankings. Meanwhile, the experience keeps shoppers enthralled.
