Got a letter from these people too saying I won a $100 giftcard and a car.  Obviously a false come on that I will toss, but I wanted to know what it was for before I did.

I got one too, from Susan Murray at Amer. Express.  Says I won cash and prizes.  Usually I toss these.  thought i'd google.

Got a blue card in the mail from Susan Murray Awards Director. It says that I need to contact them at this number to claim the prize.
