That seems like a very high price for shipping a piece of paper. I'm certain USPS will do it for significantly less, with insurance and delivery confirmation. I wonder why that isn't a viable option in this case.
"the band wants to ignore valid contracts and deprive theaters and promoters of standard revenue sources."
First off, they bought the tickets FROM THE THEATER BOX OFFICE. So no, they're not depriving the theater.
What they're doing is looking out for the FANS, which have been victimized by a far more complete and consumer-harming monopoly than Microsoft ever was. Ticketmaster should've been shut down decades ago. I've written to senators about it. These scumbags violate antitrust law in a way that should be a case study in schools around the world. Yet our "representatives" do nothing.
Ticketmaster even scalps its own tickets, which is inexplicably allowed while the same act by private citizens is illegal.
Bend over and take it, America.
Bend Over And TIcket
Having interviewed at a couple of ticketing outfits and working at one for a single day (before I decided over an meatball marinara subway at lunch that it was a scam touting outfit and I'd probably end up on Channel 4 Dispatches [small hint]), I can say that they are the most corrupt, disgusting businesses on the planet and should fuck right off this planet pretty quickly.
