Indianapolis , Fort Wayne , Gary , Evansville, South Bend

Within a stones throw of michigan, Ft. Wayne might have the best shot at a super shelf deal in the state of Indiana.  It would seem less attractive at first glance, with less retail activity than Indianapolis, and further away than major cities which can be tapped for store closing sales; but Grand Rapids was a superpower in the used Lozier micro-industry and should be considered.

Gary and South Bend have the same northern resouces available to Fort Wayne, but they also have Chicago

Ohio is another great place to look!

All in all, Indiana is located perfectly for shopping out of state.  Nearby major cities with excellent shipping options, a variety of possible liquidations, and dealers with easy access to connecting highways.
