I would be leery also. It sounds like the scam that relies on you believing that just because the bank put the cash in your account the check must have cleared. It can take a while for the bank to find out that the check you deposited is no good but by then you have already sent the item.
The item will pass to him by third party? I think that means he is going to have some guy come pick it up so there is no address the cops can go to looking for the guy who gave you the bad check.
Tell him he can send the check to his friend who can then cash it and then pay you in cash. See how that goes over, bet you never hear from him again.
