Promotion rivals Wrexham and Tranmere Rovers go head-to-head at the Racecourse Ground - and tickets have flown out the door.
It is thought sale have surpassed the 8,000 mark already, with two days until the big clash in north Wales.
Tranmere sold out their 1,800 allocation on Monday and Red Dragons fans have been busy buying this week.
Around 150 tickets remain for the match, the hosts have said.
The biggest crowd recorded this season was also involving Rovers, they playing Chester at Prenton Park earlier in the campaign in front of 7,172.
Wrexham’s average home crowd this season currently stands at 4,330 but that could well be doubled this weekend.
Excitement is certainly building for the match and Rovers manager Micky Mellon said: “We all know it’s a massive game - but they’re all massive games from here on in.”
Dean Keates, the Wrexham boss, wants his team to be “brave” when Tranmere turn up on Saturday but sees no reason why his in-form side can’t continue their great run.
There will be more build up to the match of the weekend on the National League website on Friday.
