Money Orders cannot be canceled

Did you know:
Buyers: never send money to a P.O. Box address, never use Western Union or any other kiosk type payment system. Money Orders and Certified checks cannot be withdrawn and once sent, cannot be canceled. Use extreme caution and be certain who you're dealing with. If the deal is too good to be true, it probably is. PayPal is always on the side of the buyer, I know - I was the seller to a guy with buyers remoras - I had to refund the money just because he changed his mind. It cost me 3% of the selling price to refund.
