Dollars may not grow on trees, but Dollar Tree stores work hard to bring in the green. The company operates more than 4,100 Dollar Tree, Deal$, Dollar Giant, and Dollar Bills discount stores in 48 US states and the District of Columbia, as well as about 85 stores in Canadian provinces. Stores carry a mix of housewares, toys, seasonal items, food, health and beauty aids, gifts, and books -- most priced at $1 or less. About 40% of merchandise is imported, primarily from China. The stores are located in high-traffic strip centers anchored by mass merchandisers, supermarkets, malls, and in small towns. Founded in 1986 as Dollar Tree Stores, the company reorganized in 2008 and changed its name to Dollar Tree, Inc.
