They are the same terms wherever you buy any DirecTV receiver. The terms have to do with DirecTV and TiVo subsidizing the unit if registered within 30 days (Orbit pays more than $79 for the unit). Also has to do with the high amount of money you could profit by selling the virgin access card.

I know if you buy a DirecTV receiver with cash at Circuit City, they still require a credit card so they can charge a penalty if you don't register within 30 days.
