There are none in Shops, and the ones in trades don't have a price, so I was wondering for around how much should I sell mine :)

- there's one in shops right now for 5 mil, but no one will buy it at that since they could just spend 3 mil more and get 15 more items. your best bet would be to price it at 2 mil or so, or you can just go to the advertising board and ask people to make offers.
