I ALWAYS ask for USPS money orders. I have NEVER had any problem, and if you are the buyer you have some protection. Make sure you keep your receipts!! As a seller, if you accept only USPS money orders, you will have NO problems. I sometimes accept other brands of money orders, but NEVER EVER do any Western Union bank transfers at the request of the buyer!!! This is ALWAYS ALWAYS ALWAYS a scam, ALWAYS!
