[Country] ES — private receta, pharmacy stock, and the August problem

Something I noticed reading old threads that I have not seen said out loud.

The advice on reimbursement in this community changed substantially around the start of last year, and nobody went back and updated the older posts. So depending on which thread the search engine hands you, you get two contradictory answers with the same confidence.

I have listed what I think the current consensus is below. Correct me — that is the point of posting it.
