hi all,
awhile back there was a question about this topic in the nitroplanes forum and john from nitro explained why they needed it.
i found the link to that post here=

maybe it will help to explain why they need it. it seems if you order using a card with a different adress than where the item is being shipped to or use an international CC it will also raise a flag so at that point they ask for the info.
check the link.
