E-bay craziness for a good part has a simple explanation - international bidders. Snap on does not ship abroad. With the crappy dollar snap on tools even with some premium over list are actually quite affordable to foreigners and the only way to get them without coming to the US.
Hopefully anyone else that comes along will bid on one of the earlier listings, or a later listing with no bids. That's how I got my TIP blast cabinet for the minimum reserve. I saw other listings go for the retail price. They must have needed one worse than I did.
