well rex ive had this happen to me , there is a small percentage of people that seem to think since they bought someting and they owned it , that it automaticly becomes better and worth more then new , even if they never did any improvements to such an item? happens a lot when i go to public auctions , people that bid on the same thing i do think since iam bidding on it then its worth more to them i guess ? so they pay new price + 10 % just to win it hahahahahha hhahaha so maybe one of those fella's traded it in?
