While we're on the subject of disputes... I recently won an ebay auction and paid for the item only to have the guy cancel it a day later and say "the item sold in store"--what store he's talking about is unclear. I suspect bullshit (I think it sold for less than he expected) but I have no recourse, right? He can say he doesn't have the item and there's no ebay police to go force him to ship it. Should I just take my refund and be happy?
