"Thank you for contacting PayPal.
It is against our User Agreement for a seller to charge an additional fee to accept payments from a PayPal buyer. Merchants may not charge a fee to the buyer for accepting credit card payments (often called a "surcharge"). A surcharge should not be imposed or any other fee for accepting PayPal as a payment method. A handling fee may be charged in connection with the sale of goods or services, as long as the handling fee does not operate as a surcharge and is not higher than the handling fee charged for non-PayPal transactions.
For the Terms and Conditions of the User Agreement, click the "Legal Agreement" link at the bottom of any PayPal webpage and click 'User Agreement'."
