Costco Diabetes Supplies: What You Can Buy Without Membership

Costco Diabetes Supplies Without a Membership

Managing diabetes comes with significant out-of-pocket costs, and finding affordable supplies is a constant challenge for millions of Americans. Costco is well known for its bulk pricing and steep discounts, but many people assume you need a membership to take advantage of those savings. The good news? That assumption is only partially true — especially when it comes to diabetes supplies and medications.

The Federal Law That Opens Costco's Pharmacy to Everyone

Thanks to a federal and state pharmacy access law, Costco is required to allow non-members to use its pharmacy services. This means you can walk into a Costco pharmacy without a membership card and purchase prescription medications, over-the-counter drugs, and many diabetes-related supplies at Costco's famously low prices. Some states have additional protections that further expand non-member pharmacy access, so it's worth checking your local store's policy as well.

What Diabetes Supplies Can You Buy Without a Membership?

Here's a breakdown of what non-members can typically purchase at Costco:

Insulin

One of the biggest savings available to non-members is on insulin. Costco carries Novo Nordisk ReliOn brand insulin (available in partnership with Walmart-style pricing structures at select locations) as well as name-brand insulins like Humalog, Novolog, and Lantus — often at significantly lower prices than traditional pharmacies. Some analog insulins at Costco can cost 50–80% less than at standard retail pharmacies without insurance.

Blood Glucose Meters and Test Strips

Costco's Kirkland Signature and other store-brand glucose meters and test strips are available to non-members through the pharmacy counter. Test strips in particular can be a major ongoing expense, and Costco's bulk packaging offers considerable savings. Popular brands like OneTouch, Accu-Chek, and Contour are also typically stocked.

Lancets and Lancing Devices

Non-members can purchase lancets and lancing devices at the pharmacy. Costco frequently sells these in large quantities, which drives the per-unit cost down dramatically compared to traditional drugstores.

Continuous Glucose Monitor (CGM) Supplies

Some Costco locations carry CGM supplies such as Dexcom sensors and transmitters through the pharmacy. Availability may vary by location, but these can be purchased with a prescription by non-members at pharmacy pricing.

Syringes and Pen Needles

Insulin syringes and pen needles are available at the Costco pharmacy without a membership. In many states, these can be purchased without a prescription, and Costco's pricing is often significantly lower than at CVS, Walgreens, or Rite Aid.

Over-the-Counter Diabetes Supplements

While the pharmacy is open to non-members, the general warehouse floor — including OTC supplement aisles — is members only. Supplements like berberine, chromium, or alpha-lipoic acid sold on the floor would require a membership or a member to shop for you.

Using FSA or HSA at Costco Pharmacy

Another advantage for people with diabetes is that Costco's pharmacy accepts FSA (Flexible Spending Account) and HSA (Health Savings Account) cards. This means non-members can use their tax-advantaged dollars to pay for eligible diabetes supplies like insulin, test strips, lancets, and CGM equipment — maximizing savings even further.

How to Shop at Costco Pharmacy Without a Membership

• Enter through the pharmacy entrance — Most Costco locations have a side or front entrance specifically for pharmacy customers. You generally do not need to go through the membership check.
• Bring your prescription — For medications and some supplies, have your prescription ready or ask your doctor to send it electronically.
• Ask about pricing upfront — Costco pharmacy staff can provide pricing without a membership, and prices are often dramatically lower than competitors.
• Use GoodRx or manufacturer coupons — Costco pharmacy also accepts discount cards like GoodRx, which can lower costs even further for non-members.

What You Still Need a Membership For

While pharmacy access is open to all, the rest of the warehouse requires a membership. This includes bulk food items, general health products on the warehouse floor, and non-pharmacy merchandise. If you find yourself making frequent pharmacy trips, a Costco membership may pay for itself quickly in savings on diabetes supplies alone.

Bottom Line

Costco is one of the most affordable options for diabetes supplies, and the best part is you don't need a membership card to access the pharmacy. From insulin to test strips and CGM sensors, non-members can take advantage of Costco's low prices, FSA/HSA compatibility, and bulk savings — making it a smart stop for anyone looking to reduce the financial burden of diabetes management.
