This happened in the UK a few years back. We had snow and most of the country ground to a halt.
The thing is that eBay was slow to react and the delivery dates were still showing as normal delivery times for awhile when the reality was quite different.
What the savvy-sellers did was to update their eBay listings with a banner or announcement to let their customers and potential new customers know in advance of the delay.
You can do this in WidgetChimp easily.
Add in a notification widget, add your own custom message (which could be anything you want), press save and apply the changes.
All your listings are updated and you spent less than five minutes.
Happy days! That is you working smarter not harder.
