I don't want to use authorize net or eway, can I only present the PayPal option? Also, can I take all the registration information, but then let them pay by check sent via snail mail?
By default, the extension display all the available payment methods. However , you can go to back-end of the extension to just choose the payment methods you want to use . In this case , you will just need to choose Paypal and only Paypal payment method will be displayed to donors .
