Also, I believe there's fine print saying 'The company offering this item will review your application for acceptibility' or something. That is, they have the right to review and accept/reject any 'application.' Freebizmags generally is used for those expensive cover price 'professional' magazines, and they use the employment profile and other demographic information to target the magazines to 'industry insiders'. Also, new fledgling magazines use it as a customer portal, rather than just hoping someone would luck onto them. In general, it's advertising.
That said, 150 copies of a DVD, especially a very popular movie like RotK, is really not that many. I have never gotten a DVD from them, but I am getting tens of magazines from them. Some of them are professional [Potentials, Barrons, Fortune], some of them not, but they're all paid for by somebody, and that somebody is trying to target a certain market.
