I used to tell people not to worry about the Internet so much while shopping; I felt safer dealing with reputable on-line retailers then I did dealing with a credit card in the real world; odds are good that no human being has ever seen my credit card number from an online transaction I've performed. That may not be 100% true, but certainly fewer have seen it then if I had made the purchases off-line, where at least one person would have seen it on each transaction.
