Yup...same story. I was selling a truck on Craigslist. Said he/she was an oceanographer leaving at any moment. Needed the truck for his/her dad. Asked for my email for Paypal. That's when I knew it was a scam.
These folks transfer the money and then claim they can't buy it and ask for the money back. The funds they sent were no good, so you are now in the hole for the amount you sent.
Same thing. Exactly. First text was on Saturday Sep. 7th, 2013. Same as everyone else's. Oceanographer out at sea, no calls, just emails. Wants to purchase for his father. Sets up everything. Sends a confirmation email through Paypal about money waiting, just need to send $1,500.00 through western union to transportation company to pick up vehicle. Even had the nerve to say in a text "this is not a scam and you are 100% secured with Paypal"... DO NOT BUY INTO THIS!
