Is there a fee for issuing a refund when using PayPal Payments Advanced?
If you have a Business acoount, and are in the process of issuing a full refund using the "Issue Refund" link, we'll credit your full variable transaction fee (% fee of the transaction amount). Please note that the fixed portion of the fee is not refundable. If your customer originally paid using their American Express® card, you were not charged a fixed fee and the entire variable transaction fee will not be refunded.
