Thanks for the info. I posted an item on the 4th to WA, so just sent the buyer a message saying there might be a delay. I suppose posting on the 4th, it's an each way bet whether hers would be involved or not.

What do you think the chances are of eBay removing any associated defects due to potential late deliveries? I did say to my buyer that in the event it does arrive later than the estimate, to take into consideration the circumstances if she chooses to leave feedback. I even went so far as to say to either tick yes for the feedback question, or not answer it at all.
