A number a craigslist scammer called me with. He responded to my ad for a junked car, and sent an extra large check, wanting me to sent the extra to a "mover" via western union.
Challenge these Craigslist/Kijiji scammers, send them a message: We can meet at the Police Station before your shift starts. Bring cash. (Many now have neutral areas for online sales) You'll never hear from them again.
