Not familiar with Rossman but with german DM (drogerie markt) & Muller being well represented in my country (and I presumed other ones in Europe) for over a decade or more, I thought this concept had already been established in all of Europe.
In the US, a drug store is a DM with a pharmacy in the back. There are way fewer independent pharmacies in the US nowadays as 'drug stores' have taken over.
Things are getting more interfused all the time, like there is this store 'farmacia' where I live, looks like a pharmacy, sells pills, but you can't pick up prescriptions because it's not a real pharmacy. Then the national postal offices sell gadgets and trinkets, likely because sending actual mail is in decline, and package delivery is better served by private delivery services. Gas stations have even started selling bread because of a new law that prevents grocery stores and malls from working on most Sundays.
We had a small chain in Seattle that was an oldschool holistic health store but also had a modern pharmacy attached. The one location nearest our home unfortunately did not have the pharmacy because the owner of the building also leased out to CVS across the street and the lease precluded a pharmacy from being in that location. I feel depressed going into CVS so in the end just moved my prescriptions to mail-order which is easiest (and probably most reliable) anyway.
Part of the reason independent pharmacies have declined is due to pharmacy benefit managers (PBMs). For example, Aetna owns CVS and they force you to go there.
