Seems obvious to me. There’s around 10,000 people taking advantage of the great season ticket offers. They can’t go any lower on ST prices. Therefore they need to try and bring in more casual on the day fans.
Dad and two kids is £300 for ST, that is £16 per game. No casual fan should ever pay less than that for any game. And to encourage season ticket buying, they should never pay even close to that. But I don’t see why they couldn’t do dad and two kids for say £25 for a lower category game. This deal was £50 for the WB game, and thats not going to attract anyone new.
And for casuals without kids make it £15 for lower cat games up to £25 for the biggies. It would still be a bargain, for them, and fair to ST holders.
