Tickets for the Greens’ final away game of the Sky Bet League One season, against Wigan Athletic, will remain on sale until 3pm on Thursday, 21 April.
Almost 1400 members of the Green Army have already booked their seats for the highly anticipated game which has so much riding on it for both sides.
Argyle are just a few points away from securing their spot in the end of season play-offs while Wigan are closing in on title.
With the fixture expected to draw in a bumper crowd, supporters will be able to pay on the day at the DW Stadium and can buy their tickets from windows one to three at the Main Ticket Office.
Tickets purchased on the day of the game can only be bought with cash but will see no price increase.
