2. Members only? Not when it comes to buying pharmaceuticals at low-price warehouse clubs Costco and Sam's Club. They fill prescriptions for anyone.

3. Find health care. No health insurance? Go to findahealthcenter.hrsa.gov to locate a federally funded health center that provides medical and dental care with sliding-scale fees based on your ability to pay.

4. Eye care. If you're 65 or older, you may qualify to have a volunteer ophthalmologist perform a comprehensive medical eye exam and provide up to one year of care at no out-of-pocket cost. Visit EyeCareAmerica.org.

5. Dental checkup. Treating common problems like toothaches at an E.R. can cost 10 times more than preventive care. Contact a local dental school or nidcr.nih.gov/ to get information about free or low-cost care.

6. No copay. The health care law provides for free preventive tests by participating Medicare providers. Included are wellness visits, mammograms, colorectal cancer screenings, bone density scans, Pap smears and other tests. Check with your Medicare-participating doctor. Search for the official handbook Medicare & You, which provides details on tests.

7. Join a clinical trial. You may get free medical care, often at top facilities, and possibly access to experimental treatments. There are risks, of course, and participation may take months. If you're interested, go to clinicaltrials.gov.
