I do hope the seller of that book knows the buyer will never pay that for it... there is no way.
But even so it will help set a precedent for price... stupid.

If i had to bet, i would say it is someones shell account trying to make the price high overall for his own auction.
I had this happen with my Ezio Statue... the buyer never paid and all his feedback is "buyer did not pay"... yet he had perfect feedback so these people aren't punished.
