After you get installed and working, cancel your Dish Protect and save another $8.99. If you need it later you can add it on the same phone call that needs a truck roll.
Dish changed the fee structure and rules for this. You need to keep Dish Protect for at least 30 days before you can cancel. Then if you cancel in the first 6 months they charge you a $30 cancellation fee. So you could keep it for 30 days then cancel but you would pay the initial $8.99 for the first month plus $30 cancellation to get it removed from your monthly bill.
