Shoot. A $500 price drop seems silly. I went to that sale too, but waited until the second day in spite of being tempted to arrive early like you did. I don't enjoy fighting crowds and was planning on heading down that way the next day anyway. I'd looked at the seller's other listings on FB Marketplace and was concerned that the prices might be high and that was the case. The good news is, that's probably why the box I was interested in was still there.
It's the ASCO box on the right.
I also grabbed the Plvmb screwdriver I'd spotted in a photo, hanging on the pegboard behind that bench.
The seller wouldn't budge on the price for the box, but at least he threw in the screwdriver for free. Compared to the quality/prices of the other boxes, I think got the best deal.
I just noticed the small light blue box on the floor next to the red-topped box in my first photo. I think that is also a Craftsman Heritage item (I have two == one from my great aunt Mildred and another I found later).

EDIT- I just noticed that the lathe was listed for free yesterday as well.
Apparently, that was an $800 price drop.
