It has been agreed that supporters buying a season ticket for the 2019/20 campaign by June 28 can guarantee paying the same price for their season ticket the following term.
The offer, which applies to supporters who are renewing their season tickets and first-time purchasers, also extends to all lounge memberships.
Chief executive Graham Bean said: "Following discussions with supporters, we have listened to their concerns and as a result have introduced this initiative. We hope that it is welcomed by them and helps them.
"We are really excited about next year’s campaign and hope that supporters share our vision for the team next season by taking advantage of this initiative.”
