On a high dollar item I would be a little wary of a no refund for any reason clause. Since he has a certificate from Derby on the headman I would ask to have the blue stars sent to Derby to be verified. He obviously knows that Cloud City has a good rep as he is showing another figs documantation so if he objects to that option I would stay away. As a buyer I would pay for the service of verification then if it is real pay the seller.
