Vaccinations
Many boomers who had chickenpox as a kid are being encouraged to get a new shingles shot, particularly the two-shot Shingrix vaccine because of its effectiveness. When I agreed to it at my recent physical, my doctor wrote a prescription. Enter Costco, which has an in-store pharmacy where you can get the shingles shot (or shots), as well as other immunizations including flu shots that are recommended for older folks. For people paying out of pocket, Consumer Reports found that vaccinations cost less at Costco than at drug stores such as CVS or Walgreens.
One drawback: Costco pharmacies (at least the two near me in Northern Virginia) are closed on Sundays.
