Oxford United are expecting season ticket sales to pass 4,000 for the second season in a row.
The club, which froze prices from last season, have extended the deadline for discounted tickets until 5.30pm on Monday.
It is the final opportunity to buy tickets, starting at £273 for adults, before prices rise.
More than 3,100 supporters booked their seats during the ‘early bird’ deal, which ended in April, with the demand since the end of the season taking the total past the 3,900-mark.
United chairman Kelvin Thomas said: “It is a fantastic effort by our supporters, who will back us in huge numbers once again.
“We are delighted that the numbers have remained strong for the coming season.
“I think the fans can see that we are growing stronger each year and they want to be part of it – from the first game to the last.”
Last season the U’s were the third best supported club in npower League Two, with their average gate of 7,451 only surpassed by Bradford City and Swindon Town.
United's visit to Port Vale will be screened live on TV.
The game has been switched to Monday, October 15 (7.45pm) and will be shown on Sky.
It will be the first time the U’s have had a game covered live on TV since their 2-0 win at AFC Wimbledon last Boxing Day.
United’s trip to Morecambe on Saturday, December 15 will now kick off at 1pm.
