I'm pretty sure I have come across yet another "puppy buyer" scam. This one tries the sympathy card by using the I711 text to voice operator (usually used by the deaf) to communicate and then emails. Everything sounds on the up and up right up to the point that he wants to buy every single puppy left in the litter, and ignores the request for references.
As I dug a little more, what the scam is, they send you a money order for the cost of the puppy and shipping and they ask you to send the cost of the shipping to their 3rd party shipper. You send the money and a week later your bank gets word that the money order is forged and you are out the shipping money.
One of my mom's friends did that with one of her golden pups. My mom told her it was a scam. Someone in NY wanted one of the pups, and she lives in AZ. My mom TOLD her - don't do it, it's a scam. She said, "No, no."
Sure enough. She lost the pup and was out the shipping.
