Two more waves of store closings were announced this week as the Payless shoe chain filed Chapter 11 and women’s retailer Bebe made plans to move its business online. Say goodbye to the Payless store on Rockville Pike, which had been open for just seven months, and the Bebe store at Westfield Montgomery Mall, which will close by the end of May. Payless is reorganizing and will continue to operate some of its stores, including the one at Westfield Montgomery. Bebe had no other locations in Maryland.
