A Marion County man received a call that he'd won a sweepstakes. All he had to do to collect the winnings was buy 3 pre-paid Green Dot Moneypak Cards; call a number in Idaho and give them the serial numbers.  Instead he called Marion County Sheriffs, who contacted the Oregon Attorney General's Office. Kate Medema: “This is a variation on a typical theme that’s been going on for the past few years. We believe a lot of these scams are run by someone in a different country.” She says consumers need to know that you should not have to pay to win a prize. Also, protect your personal information and report any kind of offer like this that seem suspicious.
