I am so frustrated with USPS right now! A few weeks ago I sold something (under $30) via eBay and sent it via USPS with delivery confirmation. Yesterday I received a letter from USPS stating that the mailing label came detached from the package and that they can't find the box. The letter also stated that they didn't know if the package had been successfully delivered, so I messaged my buyer and asked if she had received it. She hadn't so I immediately issued her a full refund. I have no idea how on earth USPS could have damaged the box so badly that the mailing label came off! The items were wrapped in bubble wrap inside the box and the box was very securely taped shut. The mailing label also had plenty of tape on it; there's no way it could have come off with normal handling. At this point all I can do fill out a Parcel Search Request form and hope they find the items. I am praying that my buyer does not leave me negative feedback. I apologized profusely for the inconvenience and issued a refund, so hopefully she will take that into consideration. I know it's the seller's responsibility to make sure packages reach their buyers, but I did everything I could to ensure that the box would make it there safely. It's a shame that sellers are responsible for the shipper's errors. Thanks for letting me vent!
