Sounds too good to be true personally, but on the online ticket office, ST's shown available as....
Doug Ellis – 109 seats available
Uppper – 37
Lower - 72
Holte – 1394 seats available
Upper – 1098
Lower – 296
Trinity - 555 seats available
Upper – 418
Middle – 129
Lower – 8
North - 598 seats available
Upper – 415
Lower – 183
Total = 2656 seats available to purchase online
(Not sure if they have had to remove the seats where tickets have been bought for Liverpool/Newcastle game as the ST would not be able to use their seat for that game?)
