*We soon noticed "tracking" is a rather fluid idea with the US Postal Service. They routinely won't show packages as even having been received for days after we'd dropped them off. Sometimes, the very first "tracking detail" would be a notice that the package had been delivered to its final destination! This causes so much undue stress and worry for both us and our customers, wondering where in the world our package could be. Having experienced this last with a customer named Nicholas Drew, we vowed going forward to personally hand over our eBay customer's packages only to a live human being at the postal counter. Doing this gives me an immediate receipt to share with you, dear customer, AND tracking details will be updated within minutes to show the item has been dropped off on my end and is on its way to you.
