Visiting a store does not give it the right for someone to stalk you. I don't see any reasons why (apart from the obvious $) this sort of business is not considered illegal.
It wouldn't solve all the problems but would drastically reduce the incentives.
I know one particular online car store that shares user data with insurance companies and they use that in their models to compute a "willingness" to pay more for insurance as well as of establishing the user profile.
Let's say you look a sports car but you end up buying a family van, they charge you more for that.
The very interesting part is that they create a "customer profile score" they is just a number and sell that number to other companies.
So, by pipping your habits they aggregate data and technically do not violate some local laws.8
