Paypal will offer you the option of setting up an account with them or simply paying by entering your credit card numbers.  If you don't want to use a paypal account, once you are on the payment page, please find the small link on the left of the page that says "pay with credit card."  You may also pay with cash, check, or money order.  In-person clients may pay at the time of service, but distance clients should arrange for payment to arrive in advance of their session.  All credit card and paypal payments should be received at least 24 hours in advance of the session.
