The buyer offered the seller $150 as an incentive to provide a BIN option, something that wasn't part of the original listing. Therefore, this desirable store display-sized German diecut traded for $150, a pittance. The seller should not have accepted that offer. He sacrificed hundreds of dollars - at a bare minimum - from what he would have gotten by simply letting the auction run its course. (Sustainable guide value is $900.) The moral of the story for sellers: Do your research before accepting offers for items for which you know little to nothing.
