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.
