Got a potential new one.
Buyer apparently has his house on the watch list for USPS so instead of delivering packages if no one is home they have to go to PO to pick up package.
Po then scans as delivered at PO when picked up.
So buyer contacts us saying the item was never delivered because it states that the delivery was at the PO.
