ONE SEASON DEFERMENT
Following consultation with City Matters, the Club will be offering an option for supporters to take a one season deferment on their Seasoncard for the 2021/22 season.
Supporters who are unable to attend for the 2021/22 season can defer their Seasoncard until the 2022/23 season.
If this is something you are interested in doing, please contact us on +44 (0)161 444 1894 (Option 6) to speak to a member of the team.
Requests to defer must be submitted to the Club no later than 8pm Wednesday 16th June.
Please note, should you choose to defer, your seat from the 2019/20 season cannot be guaranteed for the 2022/23 season.
Flip only spotted that last line - def wont defer - bit of a shame they cant guarantee your same seat for the season after.
