Having done a little digging, I think the £43 was a pay on the gate price, and that cheaper seats were available in advance. But it's still rubbish for a seat in the oldest, ugliest stand at Portman Road.
Count yourselves lucky. They charged Leeds fans £43, so they were saying on Twitter.
Seems outrageous to me. Why should Leeds fans, no matter how arrogant some of them are, pay more than others to watch Ipswich Town?
