PayPal is the only payment method supported by FormsCentral for now. No suggestion other payment methods are being considered. I can't think of a way you'll achieve your desires, you can't create an option within the form as to whether to pay by PayPal or not. It's either enabled for PayPal or it isn't. Create two forms - one for payment by PayPal, one for other methods - and force a choice earlier in the flow?
