@Giorgio, Further, Paypal will probably want you to return the LP to the seller in order to receive a refund. See if Paypal offers their return shipping coverage service in Italy; this will be a helpful service if the return shipping cost is expensive, since it's almost guaranteed that the seller won't cover it. I believe you have a 90 day window to leave feedback on Discogs, but double check to make sure. Also, it's not really a good idea to threaten negative feedback, because that can be considered "feedback extortion". I'm not sure if this is exclusively an ebay thing, but such threats have been used to challenge negative feedback and get it removed. I'm not 100% sure if Discogs also takes it into account if the seller contacts them, but they might, so it's best avoided.
