The offer has now been extended until 3rd May, the last day of the Football League season, and supporters who sign up before this date will be eligiable for all of the original benefits, including the 50% rebate should Town reach the Premiership and the chance to pay over seven months.
However a one-off admin fee of £10 will be charged to all adult and under 20 fans who purchase their season ticket between now and the end of the season to cover the cost of extending the early bird offer. Anyone who bought a ticket before the previous deadline will have the difference refunded.
Speaking to the Official Club Website, Chief Executive of Town Simon Clegg said: "Roy Keane's appointment has created a huge buzz not only locally but also in Ireland.
"We have therefore decided to open up the Early Bird Season Ticket offer to ensure that more Town fans can join us on this journey to future success. Home support is absolutely critical to success on the pitch and I hope that new and old supporters will want to be part of this fantastic journey.
"Supporters can be the 12th player on the pitch and we need to recreate the atmosphere from last Sunday's win over Norwich on a week in, week out basis."
