Frequently Asked Questions

Are Kirkland Signature products actually made by name brands?

Yes, many Kirkland items are produced by leading national manufacturers. For instance, Costco has confirmed partnerships with brands like Starbucks (for coffee), Bumble Bee (for tuna), and Reynolds (for aluminum foil). Costco leverages its massive purchasing power to secure high-quality production runs under its own private label.

Do I need a Costco membership just to buy Kirkland pharmacy items?

For prescription medications, most states require Costco to allow non-members to use the pharmacy. However, to purchase over-the-counter Kirkland Signature medications, vitamins, and everyday household goods from the main warehouse floor, an active membership is required.

Does Costco offer a senior citizen discount on memberships?

Costco does not offer a discounted membership tier specifically for senior citizens. The standard Gold Star membership and the Executive membership carry the same annual fee for all adults. However, the consistent savings on groceries, optical, and pharmacy items generally offset the cost of the membership very quickly.

How do I know if the bulk quantities will expire before I use them?

Always check the expiration dates printed on the packaging, particularly for cooking oils, spices, and over-the-counter medications. While medications may lose a slight amount of potency after their expiration date, cooking oils and nuts can go rancid. When in doubt, stick to non-perishable goods like paper products and cleaning supplies.
