The second sales window for Home and Away Membership saw "unprecedented demand" from Nottingham Forest fans ahead of the Premier League season.
Some supporters camped out overnight at the City Ground to secure a spot in the queue ahead of in-person sales from 10am. And there was a long line during the day once the window opened.
Fans were also able to purchase Memberships online and over the phone. Away Memberships are understood to have sold out at about 11.30am and Home ones at about 2.45pm.
