Hi, I have a question about an item that I sold on eBay and shipped on Thursday. It was sent out Express Mail, and is supposed to be delivered to the buyer on Saturday by noon. I sent it out with a tracking number and insurance via USPS. And as of 10 minutes ago, I STILL can't track the item online through the USPS website. I don't know if I'm just being paranoid, but it bothers me that I cannot see where the package is and what's going on. Has this happened to anyone else? Is this common with the U.S. Post Office? I usually ship FedEx or UPS, but the buyer wanted USPS. I even called their customer service, and got NO help. They had, literally, NO info! Please tell me that this isn't something to worry about.
