Since Rimowa is effectively owned by LVMH now, prices are the same Europe wide, when denominated in Euros.
Of Course the prices are different in Norway and Switzerland. No discounts.

The only place that sells Rimowa now aside from the boutiques is department stores where LVMH has a relationship, i.e KaDeWe in Berlin and Saks in New York.

The sales staff caters to the crowd that buys these cases. When I went to the Munich store ( the old one) months ago, the guy working at the store could not speak German, but spoke English of course. There was always a mandarin speaker .
