Have you ever entered a drawing to win a free vacation at the grocery store or something? Then, you start getting calls that you won, but it really isn't as described. Another tactic is to tell you that you won, even though you realize that you never entered any contest for the prize you supposedly won. They ask for all your personal info, so they can get your prize to you, and then you never hear from them about it again. It's good to make sure you keep track of any contests that you do enter, to avoid getting scammed. This is especially true for the ones that want you to pay something. Don't lose your money.
