Gofundme charges a pretty standard 2.9% for the credit card transaction plus $0.30 cents.
example: If you donate $100 to a Gofundme campaign then the recipient would get $96.80.
As crowdsourcing goes, they are one of the lowest when it comes to fees.
They obviously net a lot of money for theirselves because of the volume they receive being #1 in the industry but that is a trade off you take for using a well known & safe platform.
If you can donate at First Sentinel bank then I would encourage that but if you can’t make it then I’d also encourage to use the Gofundme. They can use all the help they can get right now.
