K.C. That’s a great way to save money, especially if you aren’t much of a TV watcher. I don’t personally watch much TV, but the shows my wife and I watch tend to be on cable – often the Travel Channel, Food Network, Discover, History, ESPN, and The Disney Channel for our little one. That said, I don’t think we would be heartbroken to cut the cord and go without – just as long as I can keep my fast internet connection! 😉
The question of "when does it make sense?" can easily be rephrased as "how much money can I save?" and one of the biggest factors will be the price difference between combined internet and TV service or just internet. These are also the options that vary the most widely based on where you live, and the availability of promotions or contracts that can keep prices down for a short time.
