I appreciate you attempting to donate to the site. You are welcome to try again, I use the extremely secure and easy PayPal to process payments from any credit card or you can use your existing PayPal account. However, you do NOT need to sign up for PayPal, simply click the Check Out button (see illustration below) instead of the PayPal button next to it.
Come on…give it another try…click the coffee cup below:
