The tickets became available to club members at noon today.
Season ticket holders had the opportunity over the weekend to secure their spots at the game, set for the SToK Cae Ras.
On Tuesday, March 3, at noon, whatever was left went on sale to the rest of the members.
Such was the demand that many fans reported being placed in a queue, with some even suffering digital issues as the site slowed to snail's pace and even crashed, freezing them out of the purchase.
The delay in ticket availability arose from Wrexham confirming certain broadcasting and seating conditions.

Adding another twist, Chelsea, following the competition rules, received a bigger allocation than usual.
Despite the huge game, Wrexham chose to keep prices the same as a normal Championship league fixture.
In their journey so far, Wrexham overcame league rivals Ipswich Town narrowly, thanks to a Josh Windass goal.
Prior to Ipswich, Wrexham edged Nottingham Forest in a nail-biting penalty shootout, both matches were at the iconic SToK Cae Ras.
Meanwhile, their next opponent, Chelsea, while looming large as the current World Club Cup Champions, themselves have a big fixture on their hands. Chelsea will face Aston Villa in a Premier League match on Wednesday night.
They'll be keen to return to winning ways after their recent setback of a 2-1 loss to Arsenal.
Wrexham’s players, on the other hand, will have some breathing space with no forthcoming matches until they face the London giants.
The anticipated match against Chelsea is scheduled to kick off at 5.45pm on Saturday, March 7, and will be broadcast live on BBC One and TNT Sports.
The Wrexham AFC ticketing site remains the only official way to buy Wrexham tickets.
