Be careful Karl. These scams are typically run by an organization not an individual. They first try to get the over payment refunded but they are also after getting you to deposit the check into your bank account. Once it bounces, they now have your bank routing number and your account number since it reports back through the electronic banking system to their empty account. Even if they don't get the overpayment, they will use forged documents to drain your account before you know what has happened. Then they move the money around faster than the bank can chase them trying to get it back.
