When I sold coins on Facebook I didn't like PayPal for payment I would lose money being from Canada with exchange charges. I preferred E-Transmit to your bank it didn't cost anything and I've never had a problem with scams on FB but a person has to be careful
If using a money order only accept a USPS money order. Too many of of the other kind are stolen. If meeting in person bring a bigger gun. My personal preference is a 45.
i have a drawerfull of fake money orders and checks and cashiers checks as well, lol thousands and thousands of dollars worth...paper is worthless
