Should the classifieds forums be temporarily closed?

I assumed Post Offices are closed as well.
Round here, 0uter north west London the Post Offices are
just counters in general stores, what I used to think of as sub-Post Offices,
but this suggests otherwise.

That's news to me, seeing as many people use the Post Office for withdrawing cash I would have thought they would have the same status as banks/building societies.
So what about all the people selling stuff on ebay tonight? How are they going to post anything?
