Which type of pharmacy primarily focuses on over-the-counter sales in grocery stores?

The correct answer focuses on food store pharmacies, which are typically integrated within grocery stores and primarily emphasize the sale of over-the-counter (OTC) products. These pharmacies serve a significant number of customers looking for convenience, as many people prefer to purchase their medications while shopping for groceries.

Food store pharmacies offer a range of OTC medications, including pain relievers, cold and allergy medications, digestive aids, and vitamins, making it easy for customers to find what they need in one location. The environment also encourages impulse purchases due to the proximity of various grocery items.

In contrast, independent pharmacies generally provide prescription medications, health consultations, and community health services but do not singularly focus on grocery store environments. Specialty pharmacies cater predominantly to patients with complex, chronic conditions requiring specialized medications, and mail order pharmacies emphasize convenience for prescription refills and chronic medication management rather than in-person OTC sales.
