In pursuit of their commitment to giving their customers everything from vacation packages to toilet paper to cars, national warehouse chains are constantly rolling out new perks. Sam’s Club’s newest addition: self-service health screening stations.

The company has just announced the arrival of these interactive stations for use by customers who want to perform an independent evaluation of some basic vitals. The station, made by health care supplier higi, measures blood pressure, pulse, body mass index (BMI), and weight. Users can monitor these statistics over time and share data with health trackers.

Although the stations are autonomous, Sam’s Club remains committed to more conventional health screenings. From January through October, the company holds monthly evaluations that are open to both members and non-members. On Saturday, February 11, they’ll be hosting a heart health event that will offer free cholesterol, vision, and hearing check-ups. Both the screenings and the self-service stations are available in most every Sam’s Club location that houses a pharmacy.
