You reversed the payment right? You have ground to stand on because it's in your auctions that is the only way you accept payment.
Then your buyer will understand that this is just the way it is.
Shipping to confirmed addresses is the ONLY way Paypal will stand behind you. Unconfirmed? You're out the do-re-mi.
Tell your hubster that the scam is real and is well documented in an ebook that is circulated in how to make money on ebay. Doesn't mention selling on eBay..it writes bout scamming eBay sellers.
Shouldn't be a problem if you handle it cool-headed with your customer.
GOOD LUCK!!!!!!!
