Refunds You alone are (and PayPal is not) responsible for: • Your legal and contractual obligations towards the payer for any amount you return to the payer. • Any difference between the cost to the payer of making the original payment and the value of the amount returned to the payer (for instance, as a result of transaction exchange rate fluctuations) except to the extent that the refund is an incorrect payment (see the section on Resolving Problems). See our fees for details of the fees you paid to us as the recipient of the original payment which we retain when you use the special commercial transaction refund functionality in your PayPal account, as we may allow from time to time, except to the extent that the refund is an incorrect payment (see the section on Resolving Problems).
