We live way out, and have to commute to work, but we've made a few changes. Dh and I work for the same place, and I bring ds to my office with me. There is shopping in the town where we work, so we try to do a lot of it on the way home, or combine trips if we need to go to the city. (we only do that about 2x per month).
Some other changes..I pack lunch for both of us, instead of eating out every day for lunch, which saves a ton of money (probably healthier too).
We drive a car 98% of the time, and save our truck for times when we need it (hauling horses, or for supplies for building our house). We also make up a lot in savings on heating oil by using propane instead of natural gas and buying in bulk once a year (in the summer, when prices are lowest). The house we are building will be heated by solar (radiant floor heat) so we'll be saving more there as well. The nearest natural food store is 65 miles away, so I belong to a food co-op with other people and we get a monthly delivery of things we would normally buy at the natural foods store.
