The only time I've been burned selling on ebay was by an unconfirmed user, leaving me without "seller protection." After I shipped the item, the person withdrew their original payment to meshortly thereafter. Unfortunately, another unconfirmed bidder has won an item of mine. They have paid via Paypal and are awaiting shipment. Is there some limit to the amount of time they can retrieve their money, or could they withdraw it at any time? Should I wait a few days before shipping? Any suggestions?
