Confirmed that this deal works for new and existing customers. The CSR's on the phone are not aware of this, so you have to go to Shaw Court to get this deal.
Go there with an old (broken whatever) Bell or Starchoice receiver. Tell them you want to do the Satellite trade in deal. They'll take your old satellite receiver, and give you either the HDTV DTC for free, or the HDTV PVR for $99.
Perfect for you guys that have HDTV's and Shaw, and want real HDTV content on your TV's! At $99, there's no excuse not to get HDTV heh. That and PVR functionality!
BTW - the HD package with shaw is free. As long as you subscribe to digital cable (any package), The 6 HD channels are free.
