You get a card, call, or email telling you that you won! Maybe it’s a lottery, sweepstakes, or some other prize. The person calling is excited and can’t wait for you to get your winnings. But here’s what happens next: they tell you there’s a fee, some taxes, or customs duties to pay. They ask for your bank account information, or ask you to send money via a wire transfer or to purchase gift cards and provide the card numbers.
