On January 18, I received an automated message from the seller that one of my recent eBay purchases had been shipped. It included a USPS tracking number. However, when I check usps.com with the tracking number in question, it says that "There is no record of this item." The seller tells me that I need to wait for USPS to "scan the package" and that there is an error in the system, but it's never happened before that it takes 3 days for a shipped package to appear in the USPS system (I buy quite a lot on eBay from the US). Usually, it always says "Electronic shipping info received" as soon as the seller ships the package, and then the tracking info is updated when USPS scans it, right? Or have I gotten that wrong? This time, there's just no record at all. It's a very reputable seller that I've shopped with many times before, so I'm not worried that they're trying to scam me, but I'm just very confused as to what might have happened. Has anyone else been in this situation? I've noticed in some other threads that there has been some USPS delays recently but then at least the packages seem to have entered the system correctly. What do you think might be the problem? Or is this a normal situation? Thanks so much for your help!
