In the United States alone, the company has more than 40 regional distribution centers for import flow and more than 140 distribution centers for domestic flow (Logistics, 2011). When entering a new geographic arena, the company first determines if the area will be able to contain enough stores to support a distribution center. Each distribution center supports between 75 to 100 retail stores within a 250-mile area. Once a center is built, stores are gradually built around it to saturate the area and the distribution network is realigned to maximize efficiencies through a process termed “reoptimization” (Troy, 2003).
