If you watch some of the books that get posted in this thread, and the prices they go for that exceed market common value, you realize when someone wants a book they will not be denied.
True, I've been there myself. There's another Bats #374 9.8 white pages listed - http://www.ebay.com/itm/111103350202?afsrc=1 with a BIN of almost exactly what this one went for but a opening of $79.99 - be interesting to watch it. It may go unbid.
If it gets the same money, I'm popping my 80s boxes open - I've got at least a few.
