I am not sure if I am the only one that thinks this price is insane, but you can also check it out. For the record, the highest price a "common" black N950 Developer kit that I had ever seen, was a completely sealed/unopened one, that was sold to Saudi Arabia for 3000USD. At least it was sealed for collectors, so might had a point.

This one is opened and the price is up to the sky https://www.ebay.com/itm/15446988590...0AAOSwY1Zg8L4f
