Your trouble would come in when you the address and billing history, living history is taken into account. Both Dish and DTV are cutting back on people trying to use the system that way, and DTV is heading that one. They will pass up a customer if it is even close that someone is trying to play them. Going elsewhere, you're gonna end up getting the same result, not being a new customer, and the competition is already more expensive in an everyday rate. So, out of spite, you would be doing a disadvantage after the first year.
Directv is pretty good about it. At least if the customer gets installed before Directv catches it you are good to go.
Dish on the other hand will let you go out and install the customer and come back 2 months later trying to say it's an existing customer and charge you back.
