Every large package have a tracking number, otherwise they would have a huge problem sorting and delivery problem. I know cause I used to work for UPS for 3 yrs. Now a days, I can't see any large delivery company/organization doing business without tracking number.
I am thinking people toss the receit or other documents away, so they lose track of shipping.
OK but I just shipped The Punisher CQ to a fellow freak who is in Hong Kong via USPS and they said there was no way to track the package. I kept the Customs reciept. I know UPS tracks but the price difference between UPS and USPS was like almost 200.00 more for UPS. The Buyer wanted me to ship USPS but like I said they told me there would be no tracking.
