Kmart to close its last remaining store in the contiguous U.S. Here's where it is.

Kmart is closing its last big-box store in the contiguous U.S., employees with the company told CBS MoneyWatch, capping the retreat of what was once America's dominant discount retailer. 

Kmart will shutter its location at Bridgehampton Commons mall in Bridgehampton, New York, on October 20, two workers at the store said. The location is the retailer's only remaining full-size store in the U.S. Kimco Realty, the real estate investment trust that owns Bridgehampton Commons, confirmed that Kmart is leaving the shopping center. 

A representative for Transformco, Kmart's owner, did not immediately respond to a request for comment.
