Ok, then it's worse than I thought. Here's what's wrong with this situation. 1. Out of escrow transactions are against SR rules, and if you are caught (which you probably will be at this point), you and the vendor will be banned from SR. 2. Using money orders could get you and the vendor identified, at least more easily than using bitcoins and making transactions on SR. If he asks one of his customers to send a money order to a PO box and that customer turns out to be LE, they will probably be able to identify him. In order to get himself a reduced sentence, he could turn over info about you. It's much less safe than using bitcoins for any type of transaction, and using SR, where the transactions don't exist in the block chain. 3. There is no resolution center when you did this. If you send someone a money order and don't get your package, what are you going to do? You're shit out of luck.
