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

Washington sellers should pay extra attention to expiration dates — if a box is close to an eligibility cutoff, submit sooner rather than later so transit time doesn't move it into a lower tier.

Selling unused diabetic supplies by mail is legal in all 50 states — including Washington. 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.

Frequently asked questions

Does the longer shipping time from Washington reduce my offer?

No — your offer is locked when you accept it, based on the expiration dates you submitted. We recommend submitting promptly if a box is near a tier cutoff, since offers are based on time remaining at the point we confirm your quote, not at delivery.

Is it legal to sell diabetic supplies in Washington?

Yes. Unused, factory-sealed, unexpired supplies purchased through private insurance or out of pocket can be legally sold in Washington, as in every state. Supplies labeled for Medicare or Medicaid use, or marked not for resale, cannot be accepted. Our guide to the legality of selling supplies covers the details.

Do I pay anything to ship from Washington?

No. Once you accept an offer we send a free prepaid UPS label by text or email. Drop the box at any UPS location in Washington or schedule a free home pickup at ups.com.
