I'd also check through all the paypal and ebay info you have from the sale. Sometimes you get lucky and the person put their phone number in with their paypal or ebay account. Being able to speak with someone is alot better way to get a feel for the situation. Its also a more effective way of hounding someone into getting something done than a easily deleted email.
