My husband buys a lot of antique car parts that way. He emails the seller, gets the phone number, talks to the seller to answer questions and then gets the address or the seller gives his address in the return email. He sends the money to the address the seller gives and then picks up the parts. Or sometimes he goes to look at the part first and pays with a check and takes it home. I guess I don't understand what is so fishy about the transaction.
