Season Card sales are on target to equal last seasons levels, despite the Blues failure to gain promotion to the Championship.
Supporters have snapped up thousands of Season Cards ahead of next season since they went on sale in March.
Despite last weekend's loss against Doncaster Rovers in the play-offs, Blues fans have continued to secure their seats for next season.
Adult Season Cards are available for as little as £420 from the Blues Box Office whilst Children's prices start from £50.
Director of Commercial Services Garry Adamson said: "Nearly everyone from last Season has renewed which is great news.
"We've also had hundreds of new Season Card holders as well this season which is tremendous.
"Even this week after Friday's excellent support at Doncaster fans have continued to snap up their seats and show their backing for the team going into next season."
Fans can still take advantage of the Club's Direct Debit scheme also to help spread the cost of a Season Card.
For a one off set-up fee of £15 you could spread the payments over the next three months to help lighten the load.
