I'll have to dig around for anything that Comcast sent me. Can't say I ever noticed anything with the word promo on it. I know the bills online don't say promo anywhere on them. Tomorrow though, closed all the Comcast tabs when I got off the phone. Like to keep the amount of time per day that I think about Comcast to a minimum.
No other real competition in the area. Going to be that way for the foreseeable future. I have significantly more gas company options than I do ISP options.
If my job and hobby didn't both deal with computers I would have been able to follow through with the 'I'm going to cancel' threats, but unfortunately there's no other service near me that offers anything remotely decent.
