Ultimately I spend more being an ST holder.
If I weren't, I wouldn't come to every match. When the stupid kick off times, the horrible weather and bad performance come around, I would find myself staying at home from time to time.
However, I find myself renewing each year because the club make it good value to do so.
And then, as I have the ticket, I turn up each time.
I spend more and turn up more as a result of the pricing policy.
I don't see it as a discount though: I pay the normal price.
If you only want to turn up for the 3pm matches, decent weather or big occasions, fair enough, but you're paying a pickers-and-choosers premium, I'm not getting a discount.
