Woodbury Common Premium Outlets is an outlet center located in Central Valley, New York. The center is part of Simon Property Group / Premium Outlets and takes its name from the town in which it is located. Opened in late 1985, expanded in 1993, and again in 1998, the center now has 220 stores occupying more than 800,000 square feet (72,000 m²) and is one of the largest contiguous outlet centers in the world. Due to its size, different areas are color coded to help visitors orient themselves, on weekends trolleys are available to transport shoppers from the parking lots and around the center. Due to its proximity to New York City, Woodbury Common is a major attraction for foreign tourists visiting the region. Japanese tourists are the most common as the mall advertises in Japanese publications with the knowledge that the Japanese market sells the same brands for considerably higher prices. Some stores estimate that 40-50% of their profits come from Japanese tourism. Tour buses and shuttles make daily trips from New York City, the center employs a staff of interpreters, and currency exchange and foreign shipping services are available on site. Guests are greeted in several languages including Japanese, Spanish, French and Portuguese.
