The retail and service sector is also an important part of the economy. The historic center of shopping in Grand Forks was the downtown area. Today, downtown is home to small shops and restaurants and south Grand Forks has become the major retail district in the city. Grand Forks has three large shopping centers. The oldest, Grand Cities Mall, is on South Washington Street and contains mainly small, locally owned stores as well as a Kmart. With about 80 stores, the area's largest indoor mall is Columbia Mall which is anchored by Scheels, Sears, J.C. Penney, and a small food court. The newest major shopping center in the city is the Grand Forks Marketplace power center mall which features SuperTarget, Best Buy, Lowe's, Gordmans, and several smaller stores. Depending on the relative strength of the Canadian dollar versus the American dollar, the Greater Grand Forks area attracts large numbers of tourist shoppers from Manitoba and especially from Winnipeg.
