Walgreens store hours vary by location, but many Walgreens stores close late in the evening, typically around 9 PM to 10 PM on Saturdays. Some Walgreens locations are open 24 hours, including their pharmacy services, but this is not universal and depends on the specific store. Pharmacy hours can be shorter and may include meal breaks or earlier closing times, often closing around 6 PM to 7 PM at many locations. In summary:

• Most Walgreens stores close between 9 PM and 10 PM on Saturdays.
• Some Walgreens stores are open 24 hours, including pharmacies, but these are specific locations mainly in larger cities.
• Pharmacy hours are often shorter and may close earlier than the store, around 6 PM or 7 PM.

It's best to check the specific Walgreens store location for exact Saturday hours, as they can vary widely by area and store type.
