Walmart to expand its low-cost health care centers

• Unlike traditional clinics, which are usually staffed by nurse practitioners, the health centers are run by doctors, and patients are seen in exam rooms.
• Patients are told what their care will cost before they get it, and those prices are often half of what Walmart has estimated they cost elsewhere.

The big picture: If it's successful, the move sets Walmart up to compete against companies like Walgreens and CVS, which have moved into clinics, and could give patients in rural communities more access to care.
