Hello! YOU MAY use a credit card (instead of a Paypal account) here. Oddly, you need to click the green "Continue to Paypal" button in order to use your credit card. Then click "I don't have a Paypal Account" (even if you do) or "Continue as a Guest."
If you're feeling flush, please consider adding an extra $5 or $10 to your payment amount. We depend on grassroots support to keep us growing strong. Thanks! Can't wait to see you!
