As Texas residents pick up the pieces following the devastation wrought by Hurricane Harvey, nonprofit organizations are soliciting donations — but that doesn’t always mean money.

Luckily for those along the Texas coast, America as a whole is more charitable than it’s ever been — and giving to charity has been to shown to improve one’s happiness. But not everyone has the funds to donate money to relief efforts. These days, donations from the wealthy make up the bulk of America’s charitable giving, as the average household struggles to afford such discretionary spending.

Traditional monetary donations are usually preferable, watchdog group Charity Watch told Consumer Reports, because nonmonetary donations can create logistical hurdles.

But for people who do want to pitch in and can’t afford to cut a check, here’s a roundup of unconventional philanthropic methods to support relief efforts:

Emergency Crews Rescue Those Stranded in Harvey Flooding

Donating airline miles

As Chelsea Clinton tweeted, one way to help out is by donating your unused airline miles.

Southwest Airlines, for instance, allows members of its Rapid Rewards program to support various causes by donating unused points. Participating organizations that are aiding in Harvey relief include the American Red Cross and Team Rubicon, a nonprofit that deploys emergency response teams of military veterans to regions affected by natural disasters. Southwest converts the rewards points that are donated into passes that organizations can use to fly volunteers where they are needed, said Laura Atwell, vice president of development at Team Rubicon. “For the charities, these are funds we don’t have to expend moving volunteers throughout the country for disaster relief, so we can put the money we receive toward actual relief,” said Laura Atwell, vice president of development at Team Rubicon.

Other airlines including Delta and JetBlue have similar donation programs for their rewards programs. Additionally, Airlink, an organization that connects nonprofits with airlines to facilitate relief efforts, accepts airline mile donations from United Airlines customers. For those who want to donate airline miles, it’s important to keep in mind that these donations are not tax-deductible, as they are considered gifts.

Some airlines are also looking to reward those who do make monetary donations: Both American Airlines and United are offering mileage bonuses for people who make donations, according to loyalty rewards site The Points Guy.

Transferring stock and bitcoin holdings

Those with hefty investment portfolios may want to consider spreading the wealth. Direct Relief, a nonprofit that provides free prescription medicine and medical resources to clinics in disaster-struck areas, accepts donations in the form of securities and bitcoin. People can send their brokers a letter of authorization directing the transfer of securities into Direct Relief’s account. Those without a broker can also arrange the stock transfer by contacting Direct Relief directly. Bitcoin investors can transfer their cryptocurrency using a Wallet ID available on Direct Relief’s website.

People interested in doing this should contact their tax adviser, because donating stock can allow investors to get a tax deduction for the fair market value of the security when the transfer occurred, according to Investopedia.

Hosting evacuees via Airbnb

Millions of people in Texas have been displaced by Harvey and the subsequent flooding the storm has caused. To assist in finding evacuees temporary shelter, Airbnb has set up a portal on its website dedicated to those seeking urgent accommodations. Displaced families can request a free place to stay — with service fees waived through Sept. 25.

For people who want to offer free shelter to storm victims, Airbnb also has an option to offer up available space at no charge.

Fostering pets

Many emergency shelters do not allow animals, and pet owners may find it difficult to find temporary housing that is pet-friendly if they’re forced to leave their home because of storm damage. Hundreds of thousands of pets were left behind when Hurricane Katrina battered New Orleans — often against their owners’ will — and many of them perished in the weeks following the storm, according to BuzzFeed. To prevent a similar tragedy from unfolding in Texas, animal support organizations including the Society for the Prevention of Cruelty to Animals of Texas and Austin Pets Alive have been soliciting foster households for animals affected by the storm. Currently, SPCA of Texas is at capacity for new volunteers or fosters, but Austin Pets Alive said on its website that it is looking for fosters able to keep pets until they are permanently adopted, in cases where their original owner cannot be found or determined. Austin Pets Alive is also accepting donations of pet supplies such as cat litter, collars, pet treats and food.

Mailing diapers

Have a newly potty-trained toddler and diapers to spare? The Texas Diaper Bank, an organization that provides emergency diaper kits needy families, is accepting diaper donations, as well as other items families might need such as baby wipes, baby clothing and bottles. People can drop off diapers at the organization’s San Antonio location in person or ship them. Alternatively, you can order diapers for Harvey victims through Jet.com and tack on a monetary donation. As the Texas Diaper Bank points out, relief agencies typically do not provide diapers, so this is a critical need for displaced families with young children.

Wait to donate

The impulse following a tragedy or natural disaster is to pitch in immediately. Prompt donations certainly help — but as Consumer Reports points out, the impact of Harvey will still be felt for months or years from now. Money and other donations will still be necessary in the future, so holding off on that donation might not be a bad idea if you plan to give in the future.
