The email told me I was a winner of a 2009 Nissan,in order to claim I have to go to their site which called Mobile transport company an talk to a live agent  in which this site does exist an there is a operator on standby..I have to verify I am over 18 an gave me a special code  to verify my claim. The letter started out..
My name is Julie McKeown the marketing an manager of world shipping....
Has any one received a letter in likeness to this???

That is a pretty big prize to be contacted by email, I'd like to think that if I won a prize with a value of over $15,000 they would at least call me on the phone.  Regardless anytime you have to jump through rings to claim a prize its a scam.  As soon as you show your interest by giving them back the code they ask for the juicy stuff that all scam artist look for.
