@Heyjude I asked the eBay seller. Apparently he is not part of the warehouse or the deal. He picked up (purchased) the items (don't know exactly when). He knows part of the story - these were items that never shipped to their destination. My guess is there may have been a liquidation sale. I did see a nice yellow for sale on Clist in the same area not too long ago.
