green living = lower costs.
Try to use re-useable products rather than disposable ones -- e.g. 99 cent melamine plates you can wash and re-use instead of a pack of 100 paper plates for $2.99. Use dishrags and cut-up ratty t-shirts to clean instead of paper towels. Get a package of dryer balls ($10 at Target) and stop buying dryer sheets. Make your own cleaning supplies with recipes from websites
like this one. (Be careful not to mix ammonia and bleach, if you choose to use them, and always use cold water when cleaning with ammonia.)
Also, see if there's a farmer's market nearby. Skip convenience foods. Eat less meat. When you do eat meat, buy large cuts and freeze individual-size servings. Learn how to bone and separate a whole chicken -- a large bird can feed you for at least a week for under a buck a serving. (And you can use the carcass to make your own stock for soup.) You can also make a meal large enough for a family of four, divide it into individual-size portions, and make your own TV dinners.
If you're *really* filled with the pioneer spirit, you can also switch to
reusable feminine products. Good for your body, good for the environment, and great for the wallet.
Good luck!
