I agree that 8 days is excessive but ST holders must get "first dibs2 as they will probably start with the better viewing seats and work outward so maybe giving them 3 or 4 days to purchase.

Not sure why the time is critical?  If you know any season ticket holders and you're getting a bit nervous get in touch.  As I said, not many will use their allocated 20.

The 4000 season ticket holders only need to buy 4 tickets and it pretty much rules most of the rest out. Depends on the appetite for the League Cup from the occasional fans I guess  My point is that they don’t require 9 days exclusivity
