I must to save 1000 euro to go there (including all related costs)...I can do it on 3 or 4 months...

The chance to go it's not so far after all but I must to buy the ticket now (120 euro with charges)... how can I do that??
 
I'm in the weird (and fortunate) spot of having the money saved up for a trip to InfernoFest this month - but then I had to cancel the trip due to falling ill. (Luckily, I pulled the plug on the trip before I had bought any tickets, made reservations, and the like.) So, I could pull off the trip financially, if the dollar stops falling against the Euro and Kroner.

However - is it normal to have tickets go on sale for a festival so far in advance in Europe/Norway? This is nearly 8 months before the festival dates.
