My husband made a Paypal payment for an item (not for eBay) before Christmas but they now need to refund him.  They have advised they can only process the refund via Paypal but he does not have a Paypal account.  I have a Paypal account that we both use, predominantly for eBay buying/selling and it has my husband's credit card as the default payment source but the payment does not show on my Paypal account so it must have been a guest Paypal function payment?  They have advised they can only refund to the email address used to make the original purchase which is my husband's email, not mine (even though it has his credit card on the account).

He doesn't want to open a Paypal account just to get the credit - is this a common practice?  Any idea how we resolve it?
