Through the website, select four TV's. That should be enough to get you set up with the Hopper 3. They will also want to add additional Joeys for those TV's. Don't argue, just let them schedule the installation. When the installer gets there, you can refuse those additional Joeys that you don't need. Or, just let the installer hook them up and activate them, if that is what is necessary to complete the work order. (Hook up two Joeys to each TV if you have to.) Then, after the installer leaves, call Dish to deactivate those additional Joeys, and they will send you a box with a return shipping label to send them back. Yes, this is more hassle than you should have to go through, but if you work within the system, it can be done.
My sister tried to open a new Dish account earlier this year with a purchased Wally. They made her sign up with a leased Hopper Duo to open the account instead. So, we did basically the same thing I described above, and got the system set up exactly the way she wanted it.
