The use of fictitious USPS Postal Money Orders to scam people out of money is on the rise.  In most cases the victim receives the money order and is asked to purchase gift cards for a lesser value.  They are told they can keep the difference for their time and effort.  There is usually a short due date so that the person is pressured into sending the gift cards before they know the money order is fake.
