A few years ago, I had several stores near me that went out of business - they may have changed their procedure, but if memory serves, if you have multiple stores going out of business near by, I think as they get to the close date instead of marking stuff down an insane amount (I am not sure if Toys made it past 50 or 60%) they moved everything to OTHER stores that were going out of business. I imagine they have deals with liquidators where they may just move the inventory in bulk to one buyer instead of mark stuff down to crazy levels. I don't recall toys ever getting to something like 90%, though honestly casual buyers would ****** that stuff up at 60, 70% off pretty quickly anyway if you were hoping for somehow things to last to 90%
This was a few years ago, so they may have changed and lord knows my memory isn't great. I do remember going into a couple stores and everything being gone and they said they shipped it over to store X which was a few weeks behind Store Y in the markdown schedule.
