Why do you ask for my Card Security Code?

To ensure your security when you purchase memberships on our website, you need to enter your credit card security code. Since the security code never shows up on statements or charge slips, the fact that you know what it is helps prove to us (and our credit card authorization service) that you are who you are and that you have the actual physical card in your possession, and are not someone who has stolen one of your credit card statements. Keep the code secret, and if you ever think that someone has discovered it, be sure to notify your credit card company immediately.
