A liquidation company buys the assets and sells them - down to the shelves and signs. That's why all the "Store Closing" signs are the same, because the same liquidation company shuts down many companies.
A local bon-ton had just done something similar. i'm not sure if they were bankrupt, but the store went out of business at the mall and EVERYTHING was being sold for cheap. We got a $90 coffee table (reduced already) for $6 after they took off like 90% and some other discount for that day.
Did they use the same Store Closing signs as your local Toys R Us?
