The Cornford Foundation accepts donations online via PayPal.
We chose this method because many people are familiar with PayPal, you can donate from your linked bank accounts if you have a PayPal account, you can donate using your credit/debit cards if you have a PayPal account, and you can donate using your credit/debit cards even if you do not have a PayPal account. Note: you do not have to have a PayPal account in order to donate using your credit/debit card.
If you see Dan on his run and you wish to hand him a donation instead of donating online, Dan can accept cash and checks. Dan will give you a receipt if you choose to donate via that method.
