Uh, sure. Last time's been awesome:

Even though I've only been a stewart/security - and you know why? Because it has been impossible to find tickets even with a 3x markup, lol
But this time around it should be easier since we're not playing for the championship anymore.
Places to get tickets online:
https://www.eventimsports.de/shop/20/home (they'll send to you, maybe even outside of Germany)
http://www.kartenvorverkauf-rupprecht.de/ (they'll send it to you (Germany only) or you'll need to collect them, though they might close early on match day)
http://www.kartenvorverkauf-krause.de/ (same as Rupprecht, afaik)
But even there it's basically just leftovers (after the club members have been served...or not, even as a club member you can easily end up without a ticket).
I'd offer to meet up with you, but I have no idea where I'll be in may.

The stadium sells out for like 5-6y straight (no matter the performance or venue), shit's nuts - we need a bigger stadium despite the 80k capacity :|
