I don't.

I have a 401 K which I need to start investing more in.
We TRY to eat our leftovers and not waste food at home.
I look for the cheapest place to get gasoline.
I base my food consumption and meals based on what is on sale besides necessities.
I have a bank account that distributes 1.00 to a savings account every time I use my debit card which can be anywhere from 3-15.00 a week. I always tend to take that money out though when I have something coming up to use it for. I guess I'll be saving money in there for a few months for spring break and then our trip to LR next year.
I will be watching this great thread for other tips.
