Custom Payments

GCG members or guests can now make custom amount payments to GCG on-line, using the Zeffy button below.

This page is useful for making donations, for pro-rated dues payments for new members in any amount, and also can be used to pay special fees for special events. The Zeffy button will allow you to pay using any major credit card, as noted below.

Please Note!   If you want to purchase camping passes for GSP, this is NOT the correct page.
Please go to the bottom lower-left of GSP website's "Store Page" to make that purchase, at:
    https://gsp.caves.org/store.shtml.     Use the Zeffy Form to order the appropriate pass.
Be sure to add an entry to the "Question space" whom the Camping Pass is for.     Thanks.

To donate online, click the "Donate" button at the bottom of this page.  You will be taken to the Zeffy site, where you can use a credit/debit card or a bank draft to make your payment. Once at the Zeffy site, enter the correct amount of your payment, in US Dollars. Your donation can be a one-time payment or a monthly recurring payment, if that's what you want. Then click the "Continue" button.

Fill in all your contact information, making sure to let us know what you want the donation used for. Check the tip amount you want to give Zeffy and complete your payment information. When done, hit the "Donate" button to complete the payment.
Your card won't be charged until you've hit that final "Donate" button on the site.

If you have questions or need additional information, please send an email to the treasurer@gcgcavers.com.


(NOTE: We have switched from Paypal to Zeffy to ensure all of your donation goes to GCG.)
Note Changes with Using Zeffy:

Zeffy's service is free to GCG.   PayPal, Square, and other services typically charge 3 to 5% to GCG. Zeffy supports itself through a tip (donation to themselves). Zeffy's website adds this tip onto your donation amount. That tip money goes to Zeffy - Not to GCG. You can change that amount. In the Summary section, click the arrow to the right of their suggested 17% amount and select "Other", then enter whatever tip you feel is fair.

This tip is your choice, so it's optional, but you must change it or their initial suggested amount (17%) will be added. It is not refundable.
