Ladies, I so need your advise! I sold a Celine bag on eBay, shipped it yesterday morning to the buyer using USPS Express mail with insurance coverage and signature required. It is being sent to a paypal confirmed address (a PO Box). I just got an email from the buyer and she said the box is empty! I just called USPS they told me I can file a claim for loss of content. They said the packaging could have been damaged when it was being processed, but based on what the buyer told me, when she received the bag it wasn't open and it was taped!! Could some USPS guy stole the bag inside?? I am about to cry now!! Please help!!
