Sold something on eBay, buyer asked a few questions prior to purchase as to whether the item was a genuine or not (it was genuine), then went on and won the bid.
Paid promptly, was posted on Monday and buyer is saying she hasn't received it. I paid first class delivery but not recorded or special or anything. I have 2 receipts from the post office but neither of them have a tracking number. They do confirm the item was posted and to her address. Where do I stand?
