Yeah, I would 100% stay away from doing deals over the forums. Even with OOE sales over on SR (which I do about 70% of my business with), it's still important to have a listing associated so that buyers and sellers can track shipping and leave feedback. I would suggest that if you haven't received or heard from the seller in a few days (was it a domestic shipment?) I would put up a post about it in the scam sellers stickey'd thread in the Rumor Mill section of the forums. That's a touch knock to take, and I hope it comes through for you, but it's awfully tempting for a seller to just forego shipping since you can't touch their feedback or have any form of resolution. Have to stay safe!
