More than 11,000 Pompey fans have now secured their 2020/21 flexi-season ticket.
Existing season ticket holders have until 11.59pm on Sunday, September 13 to renew for just £25.
This ensures they reserve their usual seat for the 2021/22 campaign, as well as have the chance to buy seats on a rotational basis for the forthcoming season.
Pompey fans who are not existing season ticket holders still have the chance to attend games while the capacity is reduced due to Covid-19.
The majority of seats will be made available to flexi-season ticket holders, but a proportion will be allocated to members for each match.
