Do you Need a Mail option for PPC? Is Paypal enough for Advertiser and Publishers?

Hi guys,
Looking for some more opinions on PPC.
– As an advertiser do you need to have the option to pay for your campaigns by credit card aswell as paypal?
– As a publisher do you need to have the option to have a check mailed to you?
Is just Paypal enough for both options?
Your opinions are very much appreciated.
Thanks,
Sean
