Sellers should be aware that Royal Mail are trialling a new delivery system in several UK locations. Priority is being given to Tracked 24 and Tracked 48. 1st class should be delivered as normal (but isn't), second class every other day and not at all on Saturdays. This is causing severe backlogs of both 1st and 2nd class mail (10 days late in my case).
Royal Mail hasn't released a definitive list of the trial areas, but here's what I found:
Scotland:
* Newton Mearns Mail Centre
* Cumbernauld Mail Centre
* Ayr Mail Centre
* Girvan Mail Centre
* Northern Ireland:
* Antrim Mail Centre
* Ballymena Mail Centre
* Craigavon
* England:
* Mount Pleasant delivery office (central London)
* Stoke Newington delivery office (east London)
* Malmo Road delivery office (Hull, East Yorkshire)
* Cardiff
* Darlington
* Sheffield
* Lytham St Anne's
* Preston
* Nottingham
* Coventry
* Southend-on-Sea
