I wouldn't worry about it. Their are millions of overseas purchases made by CC daily, the feds don't sit there and scan all the purchases. They have better things to do than try to scrape up a lead off of a cc statement. Local cops, maybe not, but the Feds do for sure.
Next time you should order through a Visa gift card. They sell them all over, like at walgreens or some walmarts. For $100 gift card it costs $106, but they are untraceable. All you have to do is register a fake name and adress to it by calling the number on the back. Make sure you remember the fake info u give them cuz u will have to verify that info as the billing name and adress when u make a purchase.
