I just read an interesting story, where a guy was selling a vintage truck online, and someone overseas wanted to buy it and have it shipped. The person overseas wanted to send him a huge check to cover the shipping costs. Fortunately, the guy caught on right away, but played along with it. He took the check to the FBI, and it was indeed a scam. I wonder how often innocent people get caught up in a scam like that, though. That one is actually almost believable!
