Tickets bought on the day will cost £19, a reduction in price of £2 off the normal £21 which has been in force for most of the season.
These cut price ticket rates still leave Swindon as one of the most expensive clubs to watch in Division 2.
If enough extra fans turn up for this Saturday's game then the club may think about cutting its match day prices more often, but if the attandance figure doesn't increase then don't expect to see many further cut price ticket deals later this season.
