At this time we are set up to bill our ElephantDrive customers with a credit card. We have also recently started accepting payment via PayPal. You can send us a payment at firstname.lastname@example.org . Payments accepted via PayPal must be for Yearly amounts (no monthly payments at this time). If you choose to send us a payment via PayPal, please make sure to tell us the email address associated with the account that you would like that payment to be credited towards.
Here are exact instructions on how to send money to an email address via PayPal: https://www.paypal.com/cgi-bin/webscr?cmd=p/dmo/demo_sm_1-outside
We are working on enabling automatic recurring payments via PayPal. This will also enable us to accept monthly payments.
