Hi there, @Swong56 - welcome to the community.
This is a great question! I'm actually not sure, so I reached out to our Shipping team to learn more. In the meantime, I see that you reached out to that team in a ticket, so I've made sure to escalate your case.
Same problem. Seller says the shipping label from offerup has the incorrect address. Post office delivered accordingly. Now offerup wont do anything about this issue. They will not respond to email. All my conversation history with seller has been deleted. Is this normal? Please advise.
