Sell Dexcom Sensors for Cash
Yes. Sealed Dexcom G6 and G7 sensors in their original boxes are bought for cash, by mail from any US state or in person through local buyers near you. If your prescription changed, your insurance switched you to a different CGM, or you simply have more sensors than you will ever use, those sealed boxes have real value and there is a straightforward way to convert them.

If you are unsure whether a specific part number or box variant is on the current list, the fastest check is to send a photo. A photo of the front panel gives a buyer everything they need to confirm whether the box qualifies. What to photograph and how to send it.
Two ways to sell: mail-in or local
Most sellers use the mail-in route because it is open to all 50 states and requires no in-person meeting. You get a prepaid USPS label, pack the sealed boxes yourself, and drop the parcel at any post office. Start a mail-in kit here.
If you prefer a same-day cash transaction, the buyer directory lets you enter your ZIP code and sort every listed buyer by distance from you. Buyers who are in-person list the brands and models they accept, so you can confirm before driving anywhere.
How the process works, step by step
- Photograph your sealed boxes — front panel, box count, any part numbers visible.
- Submit a quote request or text the photos directly to confirm what you have and get an offer.
- Accept the offer and receive a prepaid USPS label (mail-in) or agree on a meeting time (local).
- Pack the sealed boxes securely and drop off the parcel or hand off in person.
- Receive payment after the boxes are received and verified as sealed.
The complete mail-in guide covers every step in detail, including how to pack the boxes and what to expect after they arrive.
What is not accepted
Opened boxes cannot be bought — once the retail seal is broken, there is no way to confirm the contents are complete and undamaged. Supplies paid for through a government-covered program cannot be resold. Everything else in the accepted product list, sealed and in original packaging, qualifies for a quote.

Frequently Asked Questions
Can I sell sealed Dexcom G7 sensors I no longer need?
Yes. Sealed Dexcom G7 sensors in their original, unopened boxes are accepted for cash. You can sell by mail from any US state or find an in-person buyer through the directory. There is no public listing and no auction — you describe what you have, confirm the boxes are sealed and original, and the transaction goes from there.
Do you buy Dexcom G6 sensors?
Yes. Sealed Dexcom G6 sensors in original packaging are also accepted. If you switched to the G7 and still have sealed G6 boxes, those can be sold. The same mail-in and local-buyer routes apply to G6 stock.
Are Dexcom receivers and transmitters bought as well as sensors?
Yes. G6 receivers, G6 transmitters, G7 receivers, and G7 10-day and 15-day sensor boxes are all in the accepted product lines. Send a photo of what you have — brand, model name, and box count — and you will get a straight answer on what is currently accepted before you pack anything.
What if I switched CGM systems and have a mix of sealed G6 and G7 boxes?
That is the most common situation. People switching from G6 to G7 often have sealed sensor boxes they can never use — the systems are not interchangeable. Both G6 and G7 stock can be quoted together. Photograph the boxes, send the photos, and the quote covers everything in one transaction.
How does selling Dexcom sensors by mail work?
Start a mail-in kit at cash4teststripsusa.com/mail-in-kit. You get a prepaid shipping label, pack your sealed boxes, and drop the parcel at any USPS location. Payment is sent after the boxes arrive. You do not need to be near a local buyer — the mail-in route is open to all 50 states.
Is it legal to sell sealed Dexcom sensors?
Yes, when the boxes are yours, sealed, and were not supplied through a government-covered program. Selling sealed supplies you personally own is a normal private transaction. See the full legal guide at cash4teststripsusa.com/is-it-legal-to-sell-diabetic-test-strips for the three conditions that matter.
