I know this is a difficult time for everyone and money is tight. But I have come across this lovely organization that takes small donations to help specific families at a time. The amount you donate can be any denomination you would like. They actually encourage $1, $3 donations.
(and we all have that)
If charity and giving is something you often do, but find that you don't have the money you used to, this is a great organization for smaller amounts that still go a long way.
