Walmart is the third largest pharmacy chain in the U.S retail industry with 2017 sales as high as $20.5 billion.

What makes it a go-to pharmacy for many consumers? Affordability and convenience. Yes, Walmart offers many generic prescription drugs for just $4. Also, when your pharmacy is located in such a huge discount store, you can easily shop for just about anything else while you wait for your prescription to fill up.

Walmart also offers the lowest prices on various immunizations, over-the-counter drugs, and other personal-care/beauty products.

However, there are some drawbacks too:

• The pharmacies are not huge, and you will not find as many as CVS and Walgreens.
• Few locations offer services like in-health clinics.
• The customer service is limited and not so great because the pharmacies found in Walmart stores are not often huge and are quite busy at times.
