Yea, I got extremely surprised too when I've experienced that for the 1st time. I basically have to pray that sellers/retailers declare everything 100% correctly, so that customs in austria don't have to contact me. Once they have to contact me that automatically means I have to pay the 24€ storage fees, which is crazy.

I love the "game" too much. There's also kind of a workaround, but unfortunately not directly from retailers.
