The National League promotion final between Tranmere Rovers and Forest Green Rovers has so far sold over 15,000 tickets.
The pair meet on Sunday for a place in League Two after winning through from their respective semi-final last weekend.
The former Football League club are out in front with Tranmere already selling over 12,500 tickets.

“We’re going to enjoy the fact we’ve got to Wembley but we’re straight back to preparing for it this week,” he said.
