Glad to see a warning about another potential scammer, thanks for posting.
20+ years ago when I was first on this board selling parts, a buyer did something that I thought was a great idea. He sent his payment to me, a money order I believe, by certified mail requiring a signature. It was for some NOS parts that were $400 or so. Ever since that transaction I've done the same thing buying parts unless I was going to meet the seller in person.
Now that PayPal & other electronic methods are used I can't remember the last time & used or accepted a MO.
