Although my sites do not sell products from the U.S. for overseas shipment, in part due to the high level of fraud and the general hassle of it. I also sell fairly low priced products so it is not much of a hit on sales.

If you sell more high end products and ship them overseas, I would take additional steps beyond the credit card payment. I would call and confirm the order and request a signed purchase order to be faxed. This would not be a problem in business to business sales. In consumer sales I would call and confirm the information. Chances are a fraudster will not have a valid number or be able to properly confirm the order.

It works the other way around, so customers should expect it. One of the little things I do is a news distribution wire service which is only $35 and people call us all the time to see if we are for real, still in business, etc. This corporation has been offering this service for over ten years.
