Here are a few:
Switch to compact flourescent bulbs
Raise the deductible on your insurance; put the savings in a savings account to cover the deductible when needed
Keep the heat turned down and wear heavier clothes
Change your long distance plan so that you pay a little more per call but nothing per month (or very little)
When you are going food shopping, lump it together with buying something else at a store nearby
Go to gasbuddy.com and check gas prices then buy gas when you are doing something in the area where the price is low. You can save 10-15 cents per gallon this way
Choose your times to go out so you avoid traffic; saves gas
Join a club like Costco then buy in bulk. Get a 9-roll of paper towels instead of just one or three
Quite often there are generics of OTC meds, vitamins, etc. that are exactly the same product but cheaper
List your credit cards in order by annual percentage rate then cut the top ones in half and toss them
And finally,
Start a savings account with Emigrant Direct (et al) and have $50/month withdrawn from your bank. The $50 you saved by doing the above.
