Buyer changing address

[ML1970]

I had a buyer report an item undelivered and when I looked, the address I'd posted to was completely different from the one on the invoice. I'll put it down to idiocy on my part but I'm not sure how I could have got it so wrong. If she changed her address after tthe sale, would it show the new address on the invoice? Just a nagging doubt that maybe I'm being scammed. Any advice appreciated

You would win any item not received dispute if you posted to the paypal registered address of the buyer at the time they paid for the item.

Thanks for your reply. I'm just confused that the buyers new address appears on my invoice. I didn't think it could update. Wondered if I had made a huge mistake somehow.
