What Diabetic Supplies Can You Buy and Sell? A Complete 2026 List

Diabetic supplies are expensive, and the system that distributes them is far from efficient. Insurance ships more than people use. Prescriptions change. Brands get switched. The result is two groups of people who rarely find each other: those paying too much for supplies they need, and those sitting on sealed supplies they will never use.

Express Diabetics connects both. This guide breaks down exactly which diabetic supplies you can buy affordably without insurance, and which ones you can sell for cash — with current 2026 pricing so you know what things actually cost and what they are actually worth.

If You Need Supplies: What You Can Buy Without Insurance

Here is something many people do not realize: test strips, CGM sensors, and lancets are over-the-counter products. You do not need a prescription to buy them. That means you can purchase brand-name supplies from a reseller like Express Diabetics at well below pharmacy retail prices — completely legally.

And the retail prices are steep. To put it in current 2026 numbers:

A one-month supply of Dexcom G7 sensors averages $579 without insurance. A single box of OneTouch Ultra test strips runs about $110.73 at retail. For someone uninsured, between insurance plans, or stuck in a Medicare deductible gap, those prices make consistent diabetes management genuinely difficult.

Buying sealed, verified supplies at a discount is often the difference between testing as often as you should and rationing to save money. Here is what you can buy:

CGM sensors — Dexcom G7, Dexcom G6, FreeStyle Libre 2, and FreeStyle Libre 2 Plus. These are the highest-cost items at retail, which means they offer the biggest savings when purchased through a reseller.

Test strips — OneTouch Ultra Blue, Accu-Chek Guide, FreeStyle Lite, Contour Next, True Metrix, and more.

Insulin pump supplies — Omnipod DASH and Omnipod 5 pods, Medtronic reservoirs and infusion sets, Tandem cartridges and infusion sets.

Glucose meters and lancets — affordable, often overlooked, and essential for finger-stick testing.

Every item Express Diabetics sells is factory sealed, brand-name, and inspected for seal integrity and expiration before it ships. The product is the same one you would buy at a pharmacy. The difference is the price.

A timely note for Dexcom users: Dexcom plans to stop manufacturing the G6 in July 2026, encouraging users to move to the G7. If you are still on the G6, this is a smart window to secure sealed sensors while they remain available.

If You Have Extras: What You Can Sell for Cash

Now the other side. If you have sealed supplies you will not use, they have real cash value. Here is what Express Diabetics buys.

Test strips — Payout depends on brand and expiration. Premium brands like OneTouch Ultra Blue, Accu-Chek Guide, and Contour Next consistently command the highest prices because they have the largest installed meter bases and strongest buyer demand.

CGM sensors — The highest-value category in the buyback market, driven by their high retail prices. Dexcom G7 sensors, Dexcom G6 sensors and transmitters, FreeStyle Libre 2, and Libre 2 Plus are all in demand. With the G6 being discontinued in July 2026, G6 users with extras should sell sooner rather than later while demand remains strong.

Insulin pump supplies — Omnipod DASH and Omnipod 5 pods, Medtronic supplies, and Tandem cartridges and infusion sets. Because pods are used every three days, Omnipod users accumulate extras quickly when treatment changes.

Lancets — Sealed boxes from recognized brands. Low individual value, but they add up, and they are best included with a larger shipment.

For all sales, items must be factory sealed, unexpired with at least ten months of shelf life, in original packaging, and free of any Medicare or Medicaid program labels.

What Cannot Be Bought or Sold

To keep everything safe and above board, the following are never accepted on either side:

Opened or damaged supplies — once a seal is broken, the product cannot be verified and is ineligible.

Expired supplies — no exceptions, for accuracy and safety reasons.

Insulin — insulin requires strict cold-chain handling from manufacturer to patient. Because that chain cannot be verified in a resale, insulin sits outside the scope of what any responsible company buys or sells.

Government-funded supplies — anything obtained through Medicare, Medicaid, or another assistance program. These often carry a program label, a "Government Payee" or "DME" marking, or a red line printed on the packaging. Reselling them is illegal.

Insulin pump devices — the consumable supplies are bought and sold; the pump devices themselves are not.

Two Sides, One Simple Idea

That is the whole picture. If you need supplies, you can buy sealed, verified, brand-name products for far less than retail. If you have extras, you can turn them into cash in about a week. The supplies that would have expired in someone's drawer become the affordable supplies someone else needed.
