According to this commentary:

there have been “closing sales.”
chuckles, did your store have a closing sale?
I found a reporting website that showed a 30 sec video of the inside of the Livingston store with bare shelves. I don’t know they had a sale, but the shelves were bare and customers were stacked up like cord wood. Remember, they did all this in one day so there was no advertisements.
