In summary - for sellers, fees are going up if you use Paypal and receive payments from buyers outside of the U.S. Also you cannot tell buyers that you prefer payment in some other form if you accept PayPal. Updates tend to be dreaded, especially updates from eBay
From the new PayPal update -
We are adding a non-discouragement clause for sellers that provides:
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.
We are changing the standard transaction fee for sellers selling goods or services online to buyers outside the U.S. from 3.9% to 4.4% plus the existing fixed fee based on the currency.
We are changing the standard transaction fee for in store transactions received from buyers outside the U.S. from 3.7% to 4.2%.
