There are tons of ways to save $$ by using essential oils in your home. Essential oils are better for your health than the chemicals found in smelly stuff at the stores. EO's don't just smell wonderful, they can have wonderful health benefits for your body and state of mind.
Here are just a few that I like:
Reuse plug-in air fresheners
Freshen your TP tube
Essential Oil Air Freshener Spray (this works really well and smells wonderful)
Make your own aromatherapy massage oil
