How To Save A Mountain is a 501(c)3 non-profit corporation.
With a credit card donation, there is an additional 3% deducted by Paypal from the final contribution to How To Save A Mountain. This is why a check is better for us. However, we do understand that a credit card is very convenient because it's all done on the website, there's nothing to write, mail in, or remember.
So if having to write and mail a check will dissuade you from donating to How To Save A Mountain, whip out the plastic!
