I recently sold a bag and sent it Priority Mail and paid for Delivery Confirmation, Insurance AND Signature Confirmation. It was sent to my buyer's work address. However, the buyer informed me that the bag was simply left on the doorstep of her work and was not signed for by anyone. The tracking info says that it was delivered and "signed for" by [the name of her company, not a person's name], so I'm assuming the postal carrier simply left it there and "signed" for it him/herself. I specifically paid for Signature Confirmation because of the high value of the bag, and am really annoyed that the postal carrier just left it there. It was lucky that the buyer actually got it and that it wasn't stolen. Doesn't the postal service have an obligation to make sure that a package is signed for when the sender pays for Signature Confirmation?? What's the point of paying for Signature Confirmation, if it's just going to be left there?
