This Thursday and Friday the Communication Workers Union has planned a national strike which will seriously affect postal services across the UK, primarily Royal Mail but including many courier and other mail delivery services.
Fans who have purchased tickets for this Saturday's match against the Ospreys, by phone or online who have not yet received them should not be worried. Deliveries that were thought to be affected by the strike have been held back by the ticket office and will be placed in collections.
Fans with any concerns about their tickets should feel free to call the ticket office on 0845 345 1400, the staff will be happy to clarify the situation and confirm that your tickets are in collections.
Judgement Day IV is nearly upon us. The showpiece event, held for the fourth year running at the Principality Stadium, will see Cardiff Blues facing Ospreys, followed by the clash between Scarlets and the Dragons.
For the past two seasons you may have noticed an artist in the crowd and drawings appearing on twitter and TV. These collections of drawings were all produced from life, on the spot without the use of a camera in order to capture the vibrancy, emotion and atmosphere of the moment.
