Huddersfield Town's match against Brighton and Hove Albion next Thursday is heading for a record attendance.
The club's 'retro shirts, retro prices' initiative saw prices drop to just £10 for adult entry and fans have taken full advantage.
Only 2,300 tickets are left for the visit of the Championship's top club next week and there is still a week left for supporters to book their seats.
The attendance will likely surpass the highest home gate of this season - the 22,368 that watched Town take on Sheffield Wednesday - and could even sell out.
Town have previously sold out one match at the John Smith's Stadium - when Liverpool visited in the FA Cup third round in the 1999/00 season.
Huddersfield Town commercial director Sean Jarvis gave an update on the number of tickets left earlier this week.
He tweeted: "Brighton tickets selling well - these are what's left - RWL - 470, RWU -75, BR - 510, FMU- 527 and FML -718. So down to only 2300 remaining!"
