Ever get signed for something at Best Buy, but you swear that you never signed up for anything. Here is the trick that is used, and that I was taught from a Best Buy manager. When a customer would refuse either AOL, MSN, NetZero, magazine offers, or whatever other D-SUB we had, we’d sign you up anyway.

so basically, MSN / AOL and friends lose money even with these scams to sign up customers.
