As July comes to an end and parents prepare to send their kids back to school within a month, Walmart is hosting a “wellness day,” offering free healthcare screenings and necessary immunizations this Saturday across the country from 10am-2pm. Almost every single one of the 4,735 Walmart locations in the US will be providing aid to those who want to learn more information regarding their health status, as well as possible courses of action one can take in terms of exercise, diet, and general well-being.
