Definate Scam! Same thing happened to me when I had Shih Tzu puppies for sale last year. They would call in on a deaf persons service and the operators are not allowed to tell you that it is an overseas scam call as they are supposed to be the ears and voice only. The scammer would ask if I had any puppies left and I would say yes, I had one and the FBI is using it to find scammers and they would hang up. Before I caught on, I gave my address for the person to come see the puppies, (boy is that a catch 22, like they are going to buy if they can't come see) They emailed constantly and really did send money. I don't know how much, but it came from Canada. Scared me death, I wouldn't let the FedEx guy in the driveway, I made him stay on the other side of the locked gate! I absolutely did not want there to be any question that I had refused that envelope! From everything I read, your'e just supposed to ignore them! Mine went away when I quit advertising, it was crazy there for while! Good Luck!
