Hello, does this mean that this item is on display in the Galaxus/Digitec physical shop?

Hello, in showroom means that the drone (more than 10 pieces) are in stock in the shop!
You don't get an exhibitor but a new drone, hence the information more than 10 pieces. That's how it was for me so far when I bought showroom items.

How do you get the exhibition model for sale?
