Walmart on Friday opened up its first Walmart Health center in Dallas, Georgia. The new centers come equipped with primary care, counseling, home care, eye and hearing exams, and dentistry. The goal is to do for healthcare what Walmart's supercenter stores did for retail. Namely, to offer a breadth of services conveniently and at a much cheaper price point than rivals. For instance, a primary care visit costs $40, while a dental visit costs $25.
