I've been in Frugality Mode since we bought a co-op. Here are some of the things I've been doing
Bringing lunch to work: I live in NYC so this easily can save me $10 a day
Tea instead of coffee at work: I bought a package of tea bags from the .99 Store. So long Starbucks and hello a few bucks a day
Library instead of the bookstore
Downgrade cable: All we really watch are the basic stations and I only need HD for football. Thinking about ditching cable TV altogether after the move.
VOIP over the phone company
Tracking what you spend is also a great idea. There are plenty of online tools out there. I use www.buxfer.com
but there are plenty others.
I also have a spreadsheet I use to track not only what I am spending now, but what I used to spend before I got cheap. I then add up the "savings" as a way to keep myself motivated.
