Session tickets will opened for sale 24th June. I think these were not supposed to be sold at all, but after critism this changed.
To be honest, this is the worst organized tickets sales ever in Finland where I have been interested in. To you who critisize the town, it is not the place. It is skating Finland, maybe co-operators or new people there. Tampere has organized many international sport and other events, ice hockey, junior's track and speed, world famous artists and bands etc with no problems - and also local no-sport-events, which are domestically more popular than figure skating, for example in comic festivals in last March were 26000+ visitors/5 days.
Edit: I got a good place and I am pleased to place though the price was more I was going to spent but anyway I got tickets to competition events where I was going to. So I am pleased anyway, I will save in other things and try not to spent many on the arena. But I wonder if Skating Finland has followed Finnish law in pricing. "A single price element of a good or service may not be emphasized at the expense of the total price." I am not sure if this concludes the tickets, but I think that releasing session tickets later without people knowing there will so, it may be in "grey area", Finnish expression, I don't know if it is in use elsewhere. Probably all-event cheaper than 4-days competition ticket with less event, if some private commercial company selling things would function this way, then it would not legal here.
