Comcast is a tough nut to crack but it's doable. How much you paying Joe? Calling their corporate offices or getting escalated to their Corp Customer Care group (used to be called the Retention Dept...) can yield positive results. The problem therein lies with how well you can stomach being forced into packages with channels you simply don't want. Comcast has made it tougher the past few years.
For example: If you get a digital package with HD that has a few sports channels, they then grab a separate fee for sports redistribution. Then there's the fee that wasn't around 15+ years ago for Local channel redistribution. Then there's the rental fees and their HD service fee.
In any event, a year ago I was fed up with the high prices & fee stacking. Ended up on the phone with regional customer care and got a 2 year lock on the Digital Starter package and Blast internet. ~103 bucks a month out-the-door. I own my own modem (have forever...) and I run a TiVo box as the DVR. Come the end of this year I'll need to arm wrestle them again because the total package price will probably be in upwards of $180. Not worth it !
You should be able to get a 2 year lock on Blast or Performance (the slower tier...) internet for around 50 bucks or less per month, both being plenty fast enough for cord-cut streaming. Believe it or not, there are Comcast digital TV packages labeled 'Latino' that give you quite a few less channels, zero sports and therefore no sports fee - that are geared towards the lower income market segment and that are priced even below the 'negotiated' rate I a pay. But their website makes it nearly impossible to find & decipher those packages. We had that Latino package for several years and it was around 80 bucks a months + taxes. You get a few more Telemundo type channels with it but it's mainly just a slimmed down Digital Starter package without sports. You can always stream ESPN if you need it ... for us MNF wasn't a requirement, so we were cool not having it and saving a s h ! t ton of money. Plenty of network channel football to watch on Thursday & Sunday's.
