I just won a couple of auctions from a seller who does not take PayPal. They take PayDirect and Western Union (who mail money orders for outrageous fees) and credit cards on their personal shopping cart site. This is my first dealing with them, so I don't trust them with my CC#.
So, where's the best (and cheapest) place to buy a money order? It doesn't have to be an international MO, since we are both in the USA.
