My store was not at all different from yours. For several years I watched the bigger, busier stores close around my store, which is stuck in a C mall (which is the lowest grade in mall classification parlance, I think).
This is just my wild guess but I think that the reason why stores like ours are still around is because of the simple fact that they are unmarketable as far as real estate is concerned. Realize that the main reason why Eddie wanted Sears was because of the real estate. The good stores were almost always in prime locations, so they were ripe for the picking, and therein lies the problem as far as Sears' inability to make money is concerned: pretty much all of those good, profitable stores are no longer in service.
Stores like ours are not located in busy, successful malls, shopping centers or commercial districts, so they are pretty much worthless on the market.
You may be wondering why all these unprofitable stores are kept open, despite the drag they are on the company's profitability. Sears Holdings is liable for the property tax and upkeep on all that real estate. It would be better to utilize the real estate (keeping the stores open and get some semblance of a cash flow, even if it's not much) than to let all those stores sit empty and unproductive for years and years.
@WnlnmWS-ehx pointed out a valid question and had an interesting take on the whole situation. Felt that this post was worthy of being a thread.
