I received a message saying "Your entry last month has Won!! Goto http://bestbuywon.com/ and enter your Winning Code: 5555 to claim your Free $1000 BestBuy Gift Card."
It's a scam for Biggerbidder.net. You have to click a couple of links and sign up for stuff to get the opportunity to bid on a $1000 gift card.
