I use to do the trick where you can call in to downgrade your internet plan to the next lower tier, keep it for a month, and then call in to upgrade back to receive the promotional price again. Haven't tried that with Comcast yet though and in my case I only have internet.

None of the Mills that I'm aware of do and with half the construction going on downtown it's so dumb they didn't lay fiber down at the same time. Literally the train station on Thorndike has fiber and I could spit from my condo onto the station but it's still not available. Guess I'm stuck with Cumcast "Gigabit" which over copper isn't really gigabit and I only get a consistent 500mbps 90% the time. Only during the most dead hours would I see 800-900+ mbps consistently.
