I sold a bag on eBay for over $300. I shipped Priority Mail, with Insurance and Delivery Confirmation. I was told at the post office that signature is required when you buy insurance. I shipped Wednesday the 23rd, they tried to deliver on Friday the 25th, and I got an email today from the buyer stating how disappointed she was that I didn't ship Priority. According to the tracking number, it stated that they tried to deliver on Friday the 25th, and a notice was left, and that it can be picked up at the post office. I told the buyer this via email, and the buyer stated that she did not receive a notice. My question is, since I shipped with all of the requirements of eBay/Paypal, whose responsibility is it to make sure the item makes it to the buyer? Can she go to the post office with the tracking number and get the item? I don't know what I could possibly do at this point, the item is in a different state! Any advice would be appreciated.
