The discount period will run until June 26, with current season ticket holders' seats also reserved until this date.
Season ticket holders for the current campaign are reminded of the refund, credit or donation options. They have until April 30 to advise the club of their decision.
Any supporter who wishes to choose the credit option is asked to contact the ticket office to renew their season ticket as the credit cannot be applied to the online ticketing system.
The ticket office will be open for telephone calls each Monday, Wednesday and Friday from 10am to 2pm or can be contacted by emailing [email protected]
