The Internal Revenue Service is sending out a scam warning in relation to Hurricane Sandy.
The IRS says charity scams appear more often after natural disasters. They can come in all forms such as email, phone calls, personal solicitors and social media.
Experts say using cash is not a good idea and also be sure to know the company before making your donation.
"They should use a check or credit card or another way that provides documentation of their gift and they should be aware, they should be checking to verify the organization they want to give to if it's a legitimate organization," said David Tucker, Field Media Relations, IRS.
To see if the charity you're donating to is genuine look on the IRS and FEMA web sites. We have those links under News links.
