DETROIT (AP) — Several Kmart stores in Michigan are preparing to close next month, following dozens of others that have shuttered in the state since the company filed for Chapter 11 bankruptcy protection nearly 15 years ago. Nearly two-thirds of the 2,165 Kmart stores that were operating in the U.S. have closed since 2000, The Detroit News (http://detne.ws/2fJtv8l ) reported. Seven stores in the state are slated to close Dec. 11, including locations in Jackson and Fenton.
