3. Over-the-Counter Supplements and Vitamins

Staying healthy as you age often requires a daily regimen of vitamins, joint supplements, calcium, and fiber. Buying small bottles of these items at a standard grocery store or neighborhood pharmacy guarantees you pay a massive markup.

By switching your supplement purchases to bulk warehouse sizes, you reduce your per-pill cost significantly.

Costco’s Kirkland Signature brand is particularly valuable here. Most Kirkland supplements carry the USP (United States Pharmacopeia) Verified Mark, confirming that the product contains the ingredients listed on the label in the declared potency and amounts, without harmful levels of specified contaminants.

Stocking up on a 400-count bottle of daily multivitamins or a massive container of glucosamine chondroitin ensures you only need to shop for these essentials once or twice a year, locking in lower prices and protecting your budget from month-to-month inflation.
