I took advantage of free HD Dvr offer on DirevTv.com on the my account page. I was charged $20 fir shipping with free installation. Appt is for next wed. Since I only paid $20 instead of $50 will the installer still add a new outlet for this receiver, or will I have to pay extra for that? Does the $20 just include the tech bringing me a DVR and attaching it to an already wired outlet, or should I be able to get a new outlet installed without having to pay more?
