No one you really need to be afraid of—yet

 

The only people using these programs to keep an eye on you are the supermarkets. They don’t share the information (except with their market-research firms), they don’t mine it for personally identifying intelligence, and they don’t target you for direct-mail programs or phone calls (yet). They don’t even care if you use your real name and address when you sign up.

All they care about is your shopper profile. They want to know what you eat, what you drink, what kind of drugs you use when you get sick, how often you blow your nose, and how much toilet paper you go through in a week. And, of course, what they really care about is how much money you spend. The more you buy, the more they care.
