Did you stock up on home repair hardware only to find it collecting dust? If DIY isn't your thing, you can give your tools a new home by donating them to your local Habitat for Humanity. The items they desperately need the most are toolboxes, organizers, tool bags and tool belts for volunteers. Keeping their tools organized and handy helps them move quickly from site to site. Also, if you have drill bits or saw blades in any shape or size, those are always in need. When bits and blades hit an old nail in the demo or renovation work, it dulls them quickly, and they need to be replaced often. Learn more at habitat.org.

When should you buy conventionally grown lemons instead of organic? It's simple: If you plan on using the zest of a lemon -- the outside skin or peel -- always go with organically grown citrus. But if you're just using the juice of the lemon, it's OK to go with conventionally grown. Even with a good washing, pesticide buildup and waxes on the outside can make it tough to remove all of the chemicals before you zest a lemon. Organic lemons are grown without pesticides, so the zest is safe to use for cooking. But even with organic, be sure you wash it well: Lemons -- conventional and organic -- are touched by many hands before reaching your supermarket.

When it's time to get a new fridge, many people relegate the old one to the garage as a backup. Want to save about $150? Recycle it instead. Since the refrigerator is one of the biggest users of energy in the home, having an extra adds about 10 to 20 percent to your electric bill -- or about $150 annually. Recycling is pretty easy: Many electric companies offer a free service where they will come to your home and take away your old fridge. It will get recycled, and the Freon gas inside will also be safely removed.
