Getting screwed over on a payment for a parts purchase?

Which is why you shouldn't use "friends and family" if it's actually "goods and services" and why you should always have a tracking number as a seller.

A common thread with a lot of these online scam scenarios always seems to be a person paying with "friends and family."

Maybe check to see if there's something your bank can do about it.
