When a store is going out of business.. a lot of time, that store no longer belongs to the company. A liquidator takes over the store and sells the items.
When Service Merchandise was going under, this is what happened to them. The liquidator jacked up the prices by atleast 10%. So, when they started their going out of business sale, the original NEW price was well above the original OLD price.. then they would add the 10% off sale sign to it, making the item, really, back to it's old price.
I highly doubt that you're going to find that 60" TV for 60% off at any of their sales.
They would most likely, jack up the price or ship the higher end items to other stores to be sold there. Which happened at some of the smaller Joanns stores, once they close and the new super stores were in the area.
