Louis CK went the extra mile to work with specific venues to circumvent Ticketmaster and eliminate scalping. Some venues have contracts with Ticketmaster and could not be used. It's totally doable if you sell your own tickets, but most artists (band managers) are not up for the challenge.
He explains:
“Most tickets are $50 or less. There are no ticket fees for any shows. My agent worked hard to accomplish this by negotiating in every city and finding venues that were willing to help us make the shows affordable. In some cases, the venues and I are splitting the ticket charges between us so you don’t have to pay it. In the end it’s worth it to me because I don’t want coming to see me to be a painful choice for anyone and either way I’m making plenty of money on the tour. I sincerely hope that everyone takes advantage of this by simply buying the affordable tickets and coming to the shows. For those of you who plan to take the opportunity of the simple and cheap ticketing on this tour to make a profit at the expense of my fans, please note that we are working hard to prevent scalping and that if you resell your tickets at an unfair price, you are risking having your tickets invalidated. Also if you purchase tickets to my shows from Stubhub or other scalping sites, that ticket may not be valid.
