We do have a fireplace. For the phone thing, I did reduce my cell minutes when I discovered I wasn’t using them all.
We have a landline phone w/unlimited long distance bundled w/our TV and Internet, and it’s cheaper to keep all three than two of three, so we leave it alone.
I love to read and could easily spend a fortune on books. I have an exchange account at a local second hand book store and get most of my books at half price or less.
It goes without saying you can save a significant amount of money annually if you brown bag breakfast, coffee and lunch. I tend to eat much healthier if I bring my own.
Re: landline phone and reduced cell minutes: that’s exactly what we did. Families do what suits each individual family’s situation.
