More than 3,500 stores are expected to close in the next couple of months.
 
 Department stores like JCPenney, Macy’s, Sears, and Kmart are among the many companies shutting down stores, along with middle-of-the-mall chains like Crocs, BCBG, Abercrombie & Fitch, and Guess.
 
 Some retailers are exiting the brick-and-mortar business altogether and trying to shift to an all-online model.
 
 For example, Bebe is closing all of its stores — about 170 — to focus on increasing its online sales, according to a Bloomberg report. The Limited also recently shut down all 250 of its stores, but it still sells merchandise online.
