Background, we barely use our home phone, in fact the battery in the handset has been dead for weeks (need to get that fixed), but we keep the land line because we need it for our alarm system. Today, I made a change in our residential phone service which will save us $10 a month and $120 a year. Five minutes of time saved us $120 a year. Is $120 a ton of money? No, but its money that we have now freed up to direct towards investing, saving or even other spending priorities (even fun ones like vacation).
Take a look at your billing statements and spend five minutes once a week calling your service providers to see how you can reduce your monthly bill.
