I don’t know any independent pharmacies around me (including the one where I had my first job long ago) that were “bought out” by the chains. More like “driven out” 20-30 years ago.
If they were smart, they quit while they were still ahead rather than ride the slide down to ruin.
It happened repeatedly here. For example, all the retail pharmacies within the hospital buildings (not the hospital pharmacies for in-patients).
