27. Carpool to work
How much do you spend on gas driving to and from work? If you drive 15 miles each way five times a week, that’s a solid 150 miles per week. If you’re getting 26 miles per gallon and paying $2.80 per gallon, you’re looking at a weekly cost of more than $16 — which is more than $800 per year. Car-pool with a friend or two and you might be able to slash that expense in half. Other savings might be reaped if you opt for public transportation instead or bike to work on some days, weather permitting.
