A little long, sorry;
I cut the cord to everything but internet about 10 years ago. My wife was pregnant at the time and I just couldn't afford it.
I've been paying $40 / month for internet for just about all that time. I DO have to call and renegotiate every year or 2, sometimes having to go as far as canceling and having the spouse sign up for the "new" promotion the following day. Verizon FIOS 100/100 (although sometimes its downgraded to 75/75 depending on the promotion).
It still amazes me to hear people talk about their tv costs. $280?...a month!?!
We have chromecasts throughout, and I run a server for movies. I can't begin to fathom how much money we've saved in a decade..... but then I got into diving and watched all those savings disappear
At least when I walk in my basement it's something tangible...
I also use a VOIP box for internet calling, I was able to switch my home number to a Google Voice # for a one time fee of $20, and now I can take that # wherever I go. The box rings all the phones just like it used to. It runs through the internet so no phone bill, not one person has ever noticed a difference. I can even answer home calls while anywhere in the world.
Cell phones are $39 / phone (2) through work.
Just some ideas, my father always said "watch your pennies and the dollars will add up".
