You know, I've heard that a lot. But is it really true that no one tracks a shopper in a mall? While window shopping can be tracked on the Internet while your real-life shopping can't, that's about the only difference for a lot of people. If you use a credit card, you can be tracked on what you actually purchase quite easily (and that information is more valuable then what you simply look at, if you think about it). This particular aspect of privacy is one you gave up when you started using your credit card. The biggest difference is that on the Internet, you have no choice... you can't get out of the tracking.
