Going to Florence

Hey guys, so I've probably already told some that I'll be going to the game vs Inter Milan in the Franchi.

At the moment of writing this (2nd of February) there aren't any tickets online.

I remember there was an explanation of how to get tickets locally in Florence at the affiliated kiosks. What are the chances of them running out of tickets before the game? Would I be safer getting a ticket online for a more expensive price or should I not worry of not getting a ticket?

Thanks in advanced!

Edit: We should probably make one thread concerning visiting Florence with all the info we can compile. How would you like that?
