Fans wishing to buy tickets on the day should note that each ticket will be £3 more expensive if bought at Peterborough United's ticket office on matchday.
Disabled tickets are also available, please contact the Proact Stadium ticket office for further details.
As ever, Chesterfield fans can use the True Blue Travel service to get to the game, with coach seats costing £15 for adults and £8 for concessions (who must be accompanied by a full fare-paying adult).
The coaches will leave the Proact Stadium at 12:00pm and can be booked via 01246 209765. True Blue Travel places are now also available for buy online, though online they do carry a £1 booking fee.
