Never knew about this. I ran an eBay business ten years ago. I had sold many items on eBay and shipped from the U.S. internationally through USPS. Once it arrives at the foreign country's customs the tracking for USPS ends and depending on the country, it can take weeks for the package to finally arrive. I wonder if this was available back then. Nice post, got me reminiscing about the good old days when my only coworkers/friends were the clerks at the post office. Cheers.
