A penny saved is a penny earned today. So apply your keen sense of financial savvy to luxury items. Forget about expensive fragrant candles: make your own aromatherapy. Toss your favorite mixture of stale herbs in a pot of water (or slow cooker): simmer for a half hour, and add water as needed. When you're done, dump the residue along your favorite strip of dirt. The herbs will decompose naturally, and keep errant cats from using your yard as a litter box.
