reply to grantsa4 I have a second-hand report that they do this in the 168xx area. My friend spoke with a Comcast rep who gave better promo prices than the 800#.
We see/receive their ads once and awhile. They were on a rampage last year trying all the time to knock on people's doors. Then they stopped knocking and just started placing door knob ads everywhere. Now, I think that just gave up but I bet they'll be back soon.
80% of the routers I see as a network(Not including guest or my networks) are AT&T based. Comcast only gained about 3 customers and lost about 4 over that time period lol.
If you want better deals make sure you look out for the mailed offers(We got tons of them until we finally got internet from them) and the door to door people usually have better deals than the website.
