Yes, it's the profiteers from daswarenhaus.ch again. Please complain to digitec customer service. If many people do this, maybe it will help and Digitec will finally kick them out.
The Digitec offer is lower: Sony Alpha 7C Kit (28-60mm, 24.20 Mpx, full format)
Important to know. Sony has temporarily stopped production of the Alpha 7C.
