Running the air conditioner in your car is the thing to do if you are on the highway, but if you are in stop and go traffic it is better to roll down the windows. I tried to put the link here, but it didn't work right. There are 24 other ways to help save money on gas there too.

We have cut back on our driving, also I make a list prior to going grocery shopping and don't get anything else, I am desperately trying to potty train my 2 year old so that we can stop paying for diapers, we don't eat out as often, and I drink water from my tap. We already pay a water bill, why would I buy bottled water for myself to drink. However, I do buy little bottles for my kids to take to school for their snack.
