Possible scam on TRF?

Or an impatient seller.

Seller relisted this item today. I've had a few pms earlier with him. He insists on postal mo or westin onion payment ONLY. Both unsafe methods as far as I'm concerned. I finally agreed to the po mo and would try to get him the payment for the head only by Monday due to the inconvience of work going to the bank and then the po as they are closed on Saturdays here. Since then he has not responded and has just bumped his add knocking another +35 off.

I'm not sure this deal is on the level or if he just wants his payment and deal done yesterday.
