Hmmmm... I wanted to take a poll here and see what people think is the right thing to do in this weird circumstance I find myself in - I'm not sure just yet how I want to proceed. A buyer won a pony out of my eBay auctions this morning after a (very medium sized, but still) bidding war. They paid already, which is great!
Not great: they just messaged me to say that actually they have this pony already, so they want me to cancel the order. My first reaction is to refuse as this isn't exactly my problem and there's no guarantee the auction would go the same way if I relist the item, but is this jerky of me? Acts of grace just aren't really the way eBay works. What would you do in my place?
