I don't spend money on:
-Cable TV. I get whatever channels I get.
-Internet access. I live in the city and have wireless
-Heat. It's included in my rent.
-Collision Insurance for my car. I don't need it.
-Toothpaste/Mouthwash/Shampoo/Soap. My GFs mother hoards this stuff, because she gets rebates i guess. I just go get some when i need it
-Groceries that go bad. I try to eat everything I have before getting more.
-DVDs. I get Netflix
-Music. My friends and I share our MP3s, I have over 15,000 and haven't bought a CD in ages.
-ATM surcharges. I never go to an ATM other than my own bank unless its an emergency
