Living an altruistic lifestyle can be difficult on a budget. You want to get involved and help with your favorite causes, but you can’t afford to consistently give out of pocket.

Luckily, there are more ways to give back to nonprofit organizations than just with your checkbook. If you’re interested in living an altruistic lifestyle while still watching your wallet, check out this list of unique things you can donate besides money.

Blood
All of us have blood, but many of us may not realize we can donate. If you’re between the ages of 16-65 and in good health, you have potential to become a blood donor. Blood donations can be made every three to four months at blood drives throughout your area. With each blood donation you give, you can save up to three lives. That’s something money can’t do!

Plasma
Plasma has often been referred to as the “gift of life.” Many patients in critical condition rely on plasma donations to treat rare chronic diseases. Plasma can be donated more often than blood, and some organizations even offer compensation for your time and effort. Plus, each plasma donation you make has the potential to save up to 17 lives. Talk about impactful.

Hair
Donating your hair is as simple as a flick of the scissors, but it has a lasting impact for those in need of wigs. Research local and national hair donation organizations to see which one most suits your intentions, and then start growing! Many organizations have length minimums of eight to twelve inches to make the wigs, so make sure to check beforehand. With just a small effort, you can make a huge difference in the lives of someone struggling.

Stuff
This seems easy, but it has a massive influence on individuals and families in need. Check around your house for any gently used items like clothes, electronics, furniture or shoes you may no longer need. Or, talk to your friends and neighbors to see if any of them have items they’d like to give as well. Then, head down to your local shelter or safehouse to donate!

Organs
Do you want to make an impact even after you’re gone? Consider becoming an organ donor. While the need for transplants continues to rise in the United States, roughly only 58% of the adult population are registered as organ donors (Donate Life America). Talk to your friends and family about your intentions, and change someone’s life even when you’re no longer here.

Time
While money is useful, time is even more valuable. If you want to help others but don’t have the resources to do so, give back by giving your time. Volunteers are always needed at nonprofit organizations, so find a cause you’re interested in and contact about getting involved. If you have a special skill or career you’re able to donate, give back by providing a free resource. Or, go the old-fashioned way by helping run events, doing manual chores or working with a group.

Money doesn’t grow on trees, and giving back through financial donations can be a challenge sometimes. However, you can still make a difference by giving through ways that don’t break the bank. Because when you volunteer yourself or your resources, you not only save a penny, you save a life
