If people want to see them, they will pay any price for tickets...look at U2, their ticket prices were really high and yet the shows were packed. I personally can think of much better things to spend my money on than a concert ticket right now for anybody. In my single days we used to go to every show we could. It is much easier paying for 1 ticket as opposed to 2, plus like it's been said, add parking (when I went with friends, parking would be split at least 4 ways), and probably drinks or food afterwards and we are spending my weeks food budget on 1 night.
DC has not had any air time here that I have heard, unless they are being played when I am channel flipping and I miss them. I've seen the vdeo a few times but not in the last week. There was a lot of initial interest in them due to controversy, but how long can they sustain that? Maybe they should think of playing smaller venues so their fans can still see and enjoy them.
