1. Draft dodgers for your doors and windows:

2. Pick up a window insulation kit, caulk, and weatherstripping.
If you're not in the market for replacing your windows, then these three things will help make them as efficient as possible for keeping warm air in and cold air out.
3. Switch your ceiling fans to "reverse."

4. A little insulation in the right places goes a long way.
If you have a house built before WWII, you might not have insulation. In these cases, even if you can't afford to insulate your entire house, consider hitting the "easy" places: the attic floor and the basement ceiling. Up to 25% of heat loss occurs through the roof and 15% of your heat goes into the ground. Insulation can greatly reduce those numbers.
