Most major pharmacy chains report that 60–65% of their sales come from the pharmacy; therefore, OTC would have to account for 25–30% of their total sales for them to qualify, which is unlikely—especially since each individual pharmacy must qualify separately.
Pharmacy chains with significant market presence assert that approximately 60-65% of their sales come from pharmacies; consequently, over-the-counter (OTC) products would need to account for around 25-30% of their total revenue in order to qualify as a pharmacy-based business, which is unlikely given the individual store-by-store evaluation process.
