As a non season ticket holder, I would seriously hope that season ticket holders are classed as members without having to stump up the extra 3 quid.
You are already classed as a member by having a ST, therefore it is £20. I have a ST and bought a mate a ticket for the Leeds game. It was £25 rather than £28, and I didn't have to have a separate membership card, only my ST.
On the same theme if i bought a ticket for the wife she would not be able to sit near me. Is there any provision for moving your seat?
Yes i think you can arrange that at the time of buying. On the other hand there are no shortage of seats!
As a pass holder you get the discount - I took my dad to the Blackburn game and got the money off!! I think the club need to make more people aware of this, on the website and facebook/twitter etc. Maybe even send a letter to all pass holders this week reminding them this and ask them to help back the club for the run in and bring a friend/family member along for just £20 etc
