Sell Dexcom Sensors for Cash: G6 and G7 Seller’s Guide

Quick answer: You can sell unused, sealed Dexcom G6 and G7 sensors for cash. CGM sensors are among the highest-value diabetic supplies on the secondary market. Send a photo of the box and expiration date for a firm, same-day offer.

Dexcom sensors are expensive and in high demand — which makes them one of the most valuable supplies you can sell when you have extras. Whether you switched systems, changed insurance, or have unopened boxes you no longer need, here’s exactly how selling Dexcom sensors for cash works.

Which Dexcom products we buy

• Dexcom G6 sensors (sealed multi-packs)
• Dexcom G7 sensors (sealed multi-packs)
• Transmitters and receivers in good condition

The boxes must be factory-sealed, unexpired, and undamaged. If you’re not sure whether yours qualify, just send a photo — we’ll tell you right away.

How much are Dexcom sensors worth?

Sealed, in-date Dexcom sensors are consistently among the highest-value CGM supplies out there, often worth significantly more per box than test strips. Your exact offer depends on the model (G6 vs. G7) and how much shelf life is left. As with all supplies, the further out the expiration date, the stronger the offer — the same principle we explain in how much test strips are worth.

What condition do sensors need to be in?

To get a full offer, sensors should be:

• Factory sealed — original, unopened packaging
• Unexpired — ideally several months or more of shelf life remaining
• Undamaged — no crushed boxes, water damage, or missing components

Boxes that are close to expiring or have cosmetic damage may still have value at a reduced offer. When in doubt, send a photo.

Is it legal to sell Dexcom sensors?

Yes. It’s legal to sell personally purchased, unopened Dexcom sensors, transmitters, and receivers — they’re treated like other over-the-counter diabetic supplies. As always, supplies obtained through Medicare or Medicaid can’t be resold. For the full picture, see is it legal to sell diabetic supplies?

Selling other CGM and pump supplies

Dexcom isn’t the only thing we buy. If you also have FreeStyle Libre sensors, Omnipod pods, or Medtronic pump supplies, send them all together for one combined offer. See everything we purchase in what diabetic supplies you can sell, or start with our main guide to selling supplies for cash.
