"In representations to your customers or in public communications, you agree not to mischaracterize PayPal as a payment method. At all of your points of sale (in whatever form), you agree not to try to dissuade or inhibit your customers from using PayPal; and, if you enable your customers to pay you with PayPal, you agree to treat PayPal’s payment mark at least at par with other payment methods offered."
