I generally ask for payment by USPS money orders if I am selling a high priced item (such as a gun) here on the forum,but mostly I tell a buyer that a personal check is fine whether I know them or not. About half send payment by m.o. anyway. I also usually ship the smaller items within 24 hours of getting an "I'll take it" along with their address. The transactions I have made here easily number over 100 and I ain't been stiffed yet! I have found over the years that "gun guys" are more trustworthy than the population in general. And that's a FACT!
f.t.
What Tom said, I have never had a problem with USPS money orders.
