You can pay online here.

You will be given the option to set up repeat donations and also to create an online profile. Your profile holds your credit card and contact information to make it faster to contribute next time, but it is especially useful if you wish to modify repeated donations you have set up.

Note: Consider selecting “Bank Account” rather than “Credit or Debit Card” as the Payment Method. This will save us approximately 2% in fees and allow more of your donation to support the work of our society.
