Mark up between buying and selling by dealers

Also consider the dealer maybe throwing it all to auction. Hammer price is less than retail and he needs to cover 20% auction fees and then make a profit. So let's say the dealer thinks he will get 70% of catalogue at auction, less 20% auction fees....he would have to buy at around 30% book price to make 20%. These number can be a lot worse on mint product.
