The last full-size Kmart store in the continental U.S. is set to close in October, marking the end of the line for the retailer once known for its "Blue Light Specials." Why it matters: After the Bridgehampton,

On October 20, Kmart's last full-sized location in the mainland U.S., a store in Bridgehampton, New York, will close its doors. That leaves just one smaller Kmart in Miami and three stores in the U.S.

When the last sale is made there, it will mark the end of an era, as the Bridgehampton Kmart is the discount retailer’s last full-sized store in the United States. The last store standing will be a small location in Miami, though several stores also exist in territories such as Guam and the U.S. Virgin Islands.
