To boost appeal Millennials, Macy's is expanding a program tested in Cincinnati that enables in-store shoppers to browse items not on shelves and skip the checkout. The in-store touchscreens confirm if an item is in the store – or at any store nearby or across the country. Also being expanded are local "look book" terminals, touchscreen catalogs that replace some mannequins and show the shopper how some clothes look paired with other garments or accessories.
