Just saw this article (in Swedish) revealing a secret way to skip the duty-free store and marketplace, and thought it might be of interest here.

Here's the most relevant bit translated to English, along with the photo from the article:
The door to the walkway is usually closed and used by airport staff – but it is not forbidden to press the button on the right and go in, Arlanda's airport manager confirms to Travel News.
However, Arlanda itself prefers that travelers choose a different way, the middle of the duty-free shop.
