I actually received a 419 scam in the post the other day; it was sent from the UK. I thought 419ers had entirely switched to the internet, but apparently not. I don't know how they got my address though, I can only assume it's because of my business being listed in the public directory.
Many of these scams involve lonely Americans who are convinced to ship the stolen products overseas after they are purchased and shipped with stolen card numbers. These Nigerians are targeting the lonely, dumb and Internet connected in American and using them to steal everyone's money. Comforting.
You don't have to read it (although it is hilarious), just check the pictures :-)
