Kmart, once a dominant player in the American retail landscape, is set to close its last full-size store located in Bridgehampton, New York, on October 20. This closure marks the end of an era for the iconic discount retailer, which has seen a dramatic decline from its peak of over 2,300 locations. The closure of the Bridgehampton store will leave just one reduced-size Kmart in the entire country, highlighting the chain's struggle to compete in today's retail environment. Kmart's signature 'blue light' promotion, once a familiar sight in shopping aisles, now symbolizes the fading presence of a brand that once was a staple for shoppers across the nation.
