Sell diabetic supplies by mail from California — free shipping, same-day payment

California has the largest diabetic population of any US state — over 3.2 million adults living with diabetes — and one of the highest CGM adoption rates in the country, driven by strong insurance mandates and a large uninsured population seeking below-retail supplies.

Selling unused diabetic supplies by mail is legal in all 50 states — including California. If you have sealed, unexpired Dexcom sensors, OmniPod pods, FreeStyle Libre sensors, or test strips you can no longer use, you can convert them into cash without leaving your home. Here's how it works for California sellers, what your supplies are likely worth, and how to get the fastest payment.

How California sellers use TestStrip Buyback USA

California's large diabetic population generates significant supply surplus every year — insurance plan changes, CGM system upgrades, prescription adjustments, and estate situations all leave sealed supplies that could generate cash instead of expiring in a drawer.

Is it legal to sell diabetic supplies in California?

Yes — completely legal. California follows the same federal framework as every other state. Unused, factory-sealed, unexpired supplies purchased through private insurance or out of pocket can be legally sold. The only prohibited supplies are those labeled "For Medicare Use Only," "For Medicaid Use Only," or "Not for Resale." Check every box before submitting.
