I sold an ipod over ebay to buyer from Ukraine on July 1st, I printed shipping label via paypal so i did get a tracking LJ62 0871 263U S. I guess he hasn't received it yet because he asked where it is... I never had packages lost in the system before... And I didn't realize the tracking # on Priority Flat Rate Envelop is different than a regular USPS priority package... Is there any season mailer/ebayer out there can help me with this?
