For customers who have been expecting cancelled first day covers for the Wales 1st class error I am still waiting for them to be returned by the Handstamp Centre in Cardiff.
Unfortunately after I sent them, there was an announcement in the September Postmark Bulletin that Cardiff's SHC had closed and all covers were now being processed in Edinburgh - which leaves just that one and Mount Pleasant still operating.
Sorry for the delays - outside my control. (I received a letter from a customer in London today - it was posted on 1 September.)
