Back in the day, I sent concealed cash out all the time... but with international transactions so commonplace now, it's just not that easy. international money orders are an option, but it takes forever to sent the money order, cash/deposit it, clear it, then ship ponies out. Paypal is almost instant for the most part, and ponies can almost always be shipped out the next working day. You also double the possibility of lost mail with a MO, because something has to be shipped both ways, but I suppose it's like trading, it's always a risk.
