Hello.
I subscribed MUSE email list.
I quite want to buy a ticket on presale now!
I'm going to O2 on 3rd April 2016.
But I can't operate.
The error message says 'please enter your promotion password or offer code for these ticket.'.
I don't know it.
How can I buy?
Pleeeeese help me!!
I'm Japanese, sorry for my poor English.
