The last full-size Kmart store in the mainland U.S. is closing its doors. The Kmart in Bridgehampton, New York will shut for good on October 20th. A smaller Kmart store in Miami still stands and there are stores in the U.S. Virgin Island and Guam, where there’s no big box store competition. There were about 23-hundred locations in the U.S. when it was a top retailer. The Kmart name launched in 1962.
