RELATED: 101 Ways to Save Money Around the House 
1. Rechargeable Batteries
Remote controls, wall clocks, cameras, toys, smoke alarms. There are just too many items that take batteries around the house. Instead of shelling out big bucks for new batteries every month or so, invest in a set of rechargeable batteries . Not only will you stop wasting time running to the store, but you will also avoid the frustration of finding out that stored batteries have no charge. Just make sure to unplug the battery charger when not actively charging your batteries. Battery chargers continue to draw electricity even then.
2. Efficient Showerheads
Showering accounts for about 17 percent of residential indoor water use. High efficiency showerheads optimize the amount of water that needs to flow through your hot water heater. By installing efficient shower heads, the average American family can save about $70 on water costs per year and more on water heating costs. Look for the US Environmental Protection Agency's WaterSense label  to ensure satisfactory showerhead performance.
3. Outdoor Solar Powered Motion Activated Lights
Outdoor lights represent a challenge in many ways. By being on for several hours, they use a lot of electricity. Also, you need to remember to turn them off the next day or they keep ramping up your electricity bill. Harness the power of the sun and motion sensor technology and get solar powered motion activated lights. The lights draw energy from the sun during the day and activate only when they sense nearby movement.
4. Energy Star Washing Machine
The average American family does about 300 loads of laundry every year. An Energy Star certified washing machine uses about 20 percent less energy and 35 percent less water  than conventional ones. If your washing machine is over 10 years old or a top loading model, you need to take action! It is estimated that if every household in the US switched to an Energy Star washing machine, we would together save about $250 million every year!
5. Energy Star CFLs
- Change a single bulb for a CFL (compact fluorescent lamp), save $40 or more over the lifetime of the bulb.
- Change five bulbs for CFLs, save $200 or more over the lifetime of the bulbs.
Use this savings calculator  to get a more accurate estimate on how much you can save based on your local electricity cost and desired type of bulbs.
6. Baking Soda
At just a bit over $1.50 per pound, this is the ultimate household tool. With baking soda you can:
- Wash produce.
- Clean your grill.
- Freshen up rugs.
- Remove hard stains from clothes.
- Wash your teeth.
- Clean the dishwasher or coffee machine.
- Treat throat infections.
- Deodorize a cat litter box.
- Fight dandruff.
- Melt icy sidewalks.
- Clean toilets.
- And many more fantastic uses !
Think about how much you spend on products for each of these uses. Switch to baking soda and start saving money.
7. Foam Roller
Chiropractors and massage therapists are expensive. The average rate for a massage is about $60 per hour . This doesn't mean that you should totally give up on taking care of your body. You can take care of your pain points and "knots" on your own with a foam roller. Starting at about $5, a foam roller is the most budget-friendly way to take care of tight muscles  and prevent common injuries . From hardcore runners to couch potatoes, everybody can benefit from a foam roller.
8. Grocery and Shopping Bags
Stop wasting money on trash bags and reuse the bags that you get from grocery stores and retailers. Reduce and reuse. Grocery bags are perfect for bathroom trash cans, and bigger bags can be used for tall kitchen cans and certain diaper pails. Small grocery bags are perfect for keeping smelly kitchen residues, such as onion and garlic, contained. You save money and do your part in helping the environment.
9. Reusable Water Bottle
Stop your plastic habit! If you buy a $6 water bottle case every week, you end up spending over $300 per year. This is before redemption fees and applicable taxes. Switch to a reusable water bottle and use those savings for a credit card payment.
10. Herb Garden
Cooking at home is always cheaper than dining out. Fresh herbs are great to give your dishes that extra "oomph." However, buying fresh herbs, such as mint, basil, and parsley, can be quite expensive. If you have a spot that gets about six to seven hours of daily sunlight, such as a ledge on a kitchen window, you can have an indoor herb garden . You can pick only the amount that you need and let the rest double as a nice kitchen accent piece.
11. Olive Oil
Besides being great for cooking, olive oil helps you:
- Moisturize your skin by drinking it and adding it to warm bath tubs.
- Preserving extra-fresh herbs for later use.
- Untangle your hair and moisturize damaged hair.
- Prevent hairballs from your cat by adding a teaspoon into your cat's food.
- Free stuck zippers by dipping a cotton swab into olive oil and swabbing the zipper's teeth.
12. Canning Jar
Attention wine drinkers: Save leftover wine for up to a week  by storing leftover vino in a canning jar. It preserves the original flavor longer than just a cork and bottle, a method that only keeps the original flavor for a day or so. This tip is especially useful to prevent that $30 wine bottle from becoming vinegar in just a few days.
At Walmart you can get a whole 1.5 liter bottle of mouthwash for around $5. Here's how to stretch that bottle even further:
- Use as an antiseptic if you have no nearby alcohol.
- Make a 50/50 solution of alcohol-based mouthwash and vinegar and treat nail fungus.
- Treat athlete's foot with the same 50/50 solution.
- Apply alcohol-based mouthwash to a cotton ball to your face as an astringent lotion.
- Clean your windows.
- Deodorize your toilet with a cup of mouthwash and let it sit for about 30 minutes before flushing.
- Mix four parts of water to one part mouthwash in a spray bottle to help plants affected by mildew and fungus.
14. Spare Change Jar
Avoid the coins-in-couch cliché and get a spare change jar to keep all those coins around the house. In just a couple of months, you will be surprised at how much you can save without even trying. Encourage your whole household to chip into the spare change jar.
15. .edu Email Address
Ok, so this one isn't really an "item," but still. Current college students and past graduates that keep their .edu email active can often:
- Get free Microsoft Dreamspark software .
- Download Autodesk software , such as AutoCad and Revit, for free.
- Read the digital version of the Washington Post  without a paid subscription.

- Receive freebies from companies  through your social media activity.
- Free two-day shipping with Amazon Student .
Some high school students may be eligible also for .edu email accounts so check with the student's educational institution.
16. Cash Back and Reward Credit Cards
Competition among credit cards is constantly increasing. There is no need to be tied to a card that offers neither rewards nor cash back offers. With cash back credit cards  offering up to 2 percent, it is amazing how some companies will pay you to use their credit cards. If cashback is not your cup of tea, then there are also gas rewards cards  and airline miles programs .
17. Vacuum Sealer
This is one of the kitchen gadgets that can save you the most money. A vacuum sealer  allows you to buy items in bulk and not have any of them spoil. Think beyond meat, poultry, and seafood. How many times have you bought a two-pound basket of strawberries at low prices during the summer, only for over half of it to spoil? With a vacuum sealer, you can seal half and freeze it for later use. Zero waste.
Some people gotta have their daily Jamba Juice fix. With the cheapest smoothies starting at $4, this habit can cost you about $120 per month. Save money by making your own smoothies at home with a blender . With $20 or less, you can get a blender. Not only will you save money, but you can control the amount of sugar and extra calories that go into your drinks.
19. Electric Toothbrush
My wife has the most beautiful smile. Every time that she goes to the dentist, she passes the checkup with flying colors. Her secret is that since she turned 29, she followed the advice from her dentist to switch to an electric toothbrush . Ever since that switch, she has been able to minimize the amount of additional necessary dental work during her visits, which lowers our medical bills.
20. Twitter Account
Another non-item item,Twitter is not only for catching up with your friends and the latest news, but it can also be a major tool for savings.
- Several retailers release Twitter-specific flash deals, giveaways, and coupon codes.
- Customer service reps are under pressure to give outstanding service in this public format.
- Some companies, such as American Express , are willing to sync your Twitter account to its online platform for perks and special services.
21. Square or Paypal Here
How many times have you tried to collect from a friend who owes you money and she gets away because she doesn't have cash on her? Fix this problem by using your smartphone as a credit card processing machine with the Square  or Paypal Here  apps. Both companies ship you a credit card reader for free — nothing else is needed. Square and Paypal do take around a 2.7 percent cut but a payment in hand is better than an IOU.
If you have friends and relatives abroad, sending text messages is very convenient but gets expensive quite fast. Even if you sign up for an international SMS plan through your cell carrier, you're looking at about $0.25 per SMS, depending on carrier and country.
The reason why Whatsapp is superior than other international messaging apps is that the app is designed for virtually every smartphone . Even though my mom uses a BlackBerry and lives in Ecuador, my sister uses a Nokia and lives in Germany, my wife uses an iPhone, and I use an Galaxy S3, we are all able to text with each other from our own phones. I used to spend over $50 in international SMS and now I spend zero. That's four of us not spending a dime while keeping in touch across the world.
A crockpot  is a lifesaver for busy people. You know that eating at home is cheaper, but often there is just no time to prepare a meal. With a crockpot you just need to chop up your ingredients, throw some spices, and you are good to go. You can leave a crockpot running before leaving for work or overnight to have a meal ready for you when you come back from work or to take there for lunch.
