Sony never had my credit card info. Even if I had given it to them, it would have been as a "ShopSafe" one-time-use number. It generates a new CC number (including the card security code), with the expiration month and maximum spending limit you desire. After one vendor makes a charge to it, no other vendor can charge against the same number. And anytime you want, you can go into your online account and void a number. My credit card provider offers this service at no charge, because it reduces their exposure to fraud. I use these CC numbers any time I purchase anything online. An explanation of how it works is
