Help, any experience with Terraristika Expo?

Hello hello!

So, soon there is gonna be the quarter-annual Terraristika expo in Hamm, Germany, it's the self-proclaimed "world-wide biggest share market for reptiles" (I don't know whether that holds true, haha). I want to buy my first ball python from there, but sadly their homepage doesn't have much information besides the bare necessities, and I would like to know a little more. Has anyone here ever been there, or heard of it, or any other experiences with the Terraristika? Thank you thank you~
