How much did you pay for U2 tickets?

I honestly don't know because I have never been to their concerts- but I am also dying to go. You are right, they will probably be expensive. My brother-in-law went once and he was really close. Bono touched his hand. My bro-in-law didn't wash his hand for like two days!! He said they were really good. If I were you, start saving your money for good seats. I am sure they are totally worth it.
