I think you are missing my point. We have released blocks in the lower tier they have shown as sold out and then we have added more seats to that block. I bought some in 118 in row 20 odd, a friend bought some in the same block on the first few rows, the block sold out then another hundred plus were added in the teen rows, doesnt make any sense to me.There is no paying for un-solds in the FAC. The clubs agree what order they sell them, and had to sell those they were holding back in order to be able to sell the top tier, and then hold tickets back there instead for the same groups.
If sales were slower the lower tier ones would still be held back, and any they didn't need would be released in the last few sales windows.
Fully understand not releasing full blocks that can be returned, and I'd be amazed if we didnt have agreement with spurs that if the second allocation of level 5 wasn't taken we would not have to pay for them.
