Retail Pharmacy ~ As of December 30, 2006, the Retail Pharmacy business included 6,150 retail drugstores, of which 6,058 operated a pharmacy, our online retail website, CVS.com® and its retail healthcare clinics. The retail drugstores are located in 40 states and the District of Columbia operating under the CVS® or CVS/pharmacy® name. CVS/pharmacy® stores sell prescription drugs and a wide assortment of general merchandise, including over-the-counter drugs, beauty products and cosmetics, film and photo finishing services, seasonal merchandise, greeting cards and convenience foods, which we refer to as front store products. Existing stores generally range in size from approximately 8,000 to 18,000 square feet, although most new stores range in size from approximately 10,000 to 13,000 square feet and typically include a drive-thru pharmacy.
