Thanks Lys for your offer,
and thanks Borneoman for all your information !
It's not easy to decide...
I just came back from night shift,
and during a break at work I tried on a computer and it works,
I could go on Ticketmaster.se or Ticketmaster.com !
So it's my IP number at home who is blocked, I think...
There are a lot of categories of place/ticket to buy for the Cirkus show !
Which one did you all choose ?
