So you talk to one of them, they eventually asks for money and you send it. Eventually, you go to Laos to get laid, then come back and talk to them some more and send more money. That seems to be the trend.
but what if, you get all their numbers, buy yourself a plane ticket, call them the week before and talk to them, then fly over and do your deed, then come back? Okay, you'll probably have to pay some money while you're there, but you'd save on the prepaid and post payments, right?
