I have the Craftsman version of that set. From back when Craftsman was good stuff.
We had a couple of Sears Surplus stores around. They sold returns and the last few of an item, that wasn't worth putting in the catalog. So, with the tool sets, they would make a change to what was in the kit, so it had a new part number, and they would sell the old part number at a discount.
One evening, we were shopping, and after I checked the tool area, I was wandering around. Up front, behind the counter was a stack (some 6+ feet high) of boxes. Taped to the stack was a copy of a catalog page of tools. I couldn't read it, so I asked the guy which tool set that was. He said, THE tool set. ??? He said, THE BIG ONE, the centerfold of the tool catalog. The one that at the time was well over $4000. I asked how many sets. He smiled and said, that is ONE set. How much??? $900. WTF?! So what happens is something is missing. He said come back with a list and he would order and replace anything missing. The kit FILLED my car.
It was missing 3 things. I took the list, he ordered 2. The third was no longer available (maybe the reason for the kit contents change), so he refunded me for that tool. At full retail.
