It is a massive pain that our PO is closed. Hopefully, whatever the issue is, it will be resolved and the PO will open promptly, as it must be causing delays for commercial and domestic customers alike! I used the King St PO last week. Not the most friendly, but there we go. There is one in Ealing Common (I have not ventured to this one as of yet), by the tube, so that is another option which isn't too far away.
