So in some ways this is similar to Blockbuster. Ignoring much of the debt brought on by that buyout it appears they simply could not adapt the shopping preferences of their market. Yes the debt was a dark cloud hanging over them but if what the article implies is true it was only a matter of time before this result would have occurred; it might have been a more stable transition but it would have come.
I also believe that not only did they succumb to online retailers but their price point was easily undercut by the dollar style stores in some markets and besides pricing the retail locations were not always ideal
