If you're using a VISA debit rather than a switch card, you should be fine using it anyway. Also, get a credit card if you're going to make a habit of buying like this since the Consumer Credit Act offers you far more protection that your debit card does. Finally, be wary of buying from the US since you can incur heavy customs and inport charges. As for a money order, something like Western Union sounds about right, but it's like posting cash - ie. NO protection for you whatsoever!
