I advertised an item collection-only but didn't have addresses for Dispatch, Return or Payment and Collection in my account info.My item has sold but the buyer doesn't know where to collect it from.I have now entered all the addresses. Is it too late?Should I ask the buyer to cancel and rebuy? Will they then be able to see the collection address?

Has the buyer paid? They have to pay through Ebay and you won't be able to message them your full address until they have paid.
