I'm sure it's also so the company you bought from get demographic info about you.

BTW, I realized that Car and Driver sells its subscription info to people. I received a solicitation via mail for Sprint that had my name mispelled exactly the same way Car and Driver lists me on the address label. I also only use my first intitial "S" many times when ordering online or for magazine subscriptions. That way, like with the Sprint mail, I know for sure that they got my info from another company online.
