If you are still thinking about dropping cable TV, then call Comcast and say you are disconnecting your service. They will give you an incentive to stay. Ask my parents and the dozens of others who call into comcast every 6 months. My parents haven't paid full price for Comcast service in over 5 years.
Not in my case. They told me if I left then that's your prerogative. It wasn't until I actually cancelled service that they called me asking why I left.
