Many of us choose to buy our holiday gifts online and have them delivered in lieu of going to the mall. When buying gifts online, opt for ground shipping instead of express shipping; it's a cheaper and more fuel-efficient way of delivering gifts. If you want to double the efficiency of your packages, have them sent to your place of work instead of to your home. Since delivery companies like UPS and FedEx already make stops at corporate offices, they won't have to make additional stops to infrequently visited homes. This helps cut down on fuel usage.

Denim jeans are one of the most-owned items by both men and women in the United States, so it makes sense to take care of them properly so they look good for longer. First, always wash jeans in cold water and turn them inside out. This will help retain their shape and won't hurt the finish of the jeans. Skip the dryer and let them dry out on a clothesline. You can even just drape them over a hanger and hang it on a door if a clothing line is not an option. Finally, when it's time to get new jeans, donate your old ones. The most re-sold item at Goodwill is jeans, so it will gladly take them from you to raise money for its charitable works.

Sick of scrubbing your shower to keep it clean from mold and mildew? Try this easy and nontoxic preventative method the next time you shower: Using the residual water and steam from your early morning shower, sprinkle table salt all over the tile, floors and even the shower curtain. The moisture from the shower will help the salt stick to all of the surfaces. Let it sit all day (and even overnight), and the next time you shower, the salt will wash down the drain. The anti-microbial attributes of salt help fight mildew and will keep your shower clean for weeks.
