I'm sure there used to be more come to the game for a tenner type offers. I know I took advantage of some when I couldn't regularly get due to family commitments.
They did some Tuesday & Saturday doubles which were useless for those who didn't have a ST because of either evening work or weekend work. Offers for games of their choosing were a poor substitute for a wider range of ticketing options. Flexi-tickets were tried briefly and then ditched. I didn't understand why it mattered how many used them.
I thought it might be on Sky but it's not. You may not find any "hooky streams" but if you do let us know !
Works out well for me, I've got back surgery next Monday (subject to covid test),so I'll be isolating. Be able to watch game now. Can you west stand ticket holders decide on the day whether to select a seat and attend, or is there a deadline?
