The big thing right now is fake postal money orders and bad certified checks. Both the USPS and the banks are having a terrible time catching the bad ones. I'm doing a three week payment processing and clearing time now just because so many have come back bad in the last year. WTH? And with Paypal doing the free shipping back I'm not even filling those emailed direct mail orders until 3 weeks go by so they don't charge back. Anyone else having issues with those?
