Thanks but I realize that. Today when I went from the tour page, just to see where it would take me, I was redirected to different sites on 2 occasions. First was axs.com and the second time was Eventim. I just thought this was a little strange after everyone seems to mention Ticketmaster.
All the sites advise creating an account/billing details beforehand to increase your chances of getting a ticket which is why I asked the question.
