It has appeared to me like Sears has been slowly dying for years. The corporate strategy seems to be to sell buildings, property, and brands, extracting as much value from the system as possible before the shutdown.
There was a time when Sears was the largest corporate employer in the country. It had the premier mail order business, lifetime warranties, and a network of stores. You could buy a car, a gun, or a house, along with everything you needed to outfit the house and all the occupants.
