    Costco offers free health care screenings for a number of issues, and they aren't only for members. Nonmembers as well can get free screenings for diabetes, osteoporosis and heart health at warehouses across the country. To find a schedule of free screenings, visit Costco's pharmacy site and look for the "health & wellness clinics" link.

    Costco locations with a hearing aid center will also provide free hearing tests by appointment, while the pharmacy offers flu shots for $14.99 to both members and nonmembers.
