It's funny to hear about how it "should be done".
We didn't know any of this when we moved back here. We rocked up at the border with a van full of our stuff, the border guy asked what was in the van, Husband said (in Swiss German, maybe that made the difference) "all our stuff, we are moving back to Switzerland". Border Guy "Very good, now go over there and buy a vignette" ...... that was it
