The Saints are to extend their ticket office opening hours this week to make sure fans can book their place at the Scottish Communities League Cup semi-final.
The Buddies will go into battle against Celtic at Hampden on Sunday and it is hoped the black and white army will be out in force.
To help with this, the ticket office at St Mirren Park will be open for business tomorrow and Friday, from 10am until 4pm and from 5pm to 7pm.
Tickets can also be bought today, from 10am until 2pm, and on Saturday, from 10am until 1pm.
In addition, a special ‘parent and child’ supporters’ bus will operate from St Mirren Park to Hampden to help families get to and from the big match.
