Continuous glucose monitors have become one of the most valuable categories of unused medical supplies — and for good reason. A single box of Dexcom G7 sensors retails for $350–$400 without insurance. Freestyle Libre 3 sensors run similar prices. When people switch systems, upgrade to a newer model, or stop needing CGM after lifestyle changes, they often end up with hundreds or thousands of dollars worth of sealed, unused sensors sitting in a drawer.
Here's everything you need to know about selling unused CGM supplies in 2026 — what they're worth, what makes them sellable, and how the process works.
What CGM Supplies Can You Sell?
The most in-demand CGM supplies for resale:
- Dexcom G7 sensors — highest demand, premium prices
- Dexcom G6 sensors — still widely used, strong market
- Freestyle Libre 3 sensors — very popular, easy to sell
- Freestyle Libre 2 sensors — good market, slightly lower value
- Eversense implantable CGM components — niche but sellable
- Medtronic Guardian CGM sensors — sells to Medtronic pump users
- Dexcom G7 transmitters — if separate (G7 integrates, but G6 needs transmitter)
Transmitters for older systems (Dexcom G5, G6) are also sellable. Dexcom G7 integrates the transmitter into each sensor, so those are simpler.

What Makes CGM Supplies Sellable?
For your CGM supplies to be sellable at good prices, they need to meet a few criteria:
Must be sealed: CGM sensors must be in their original, factory-sealed packaging. Once the pouch is opened, the sensor is not sellable. Buyers need to trust that the sensor is sterile and in original condition.
Must not be expired (or close to it): This is the biggest factor. CGM sensors with 9+ months until expiration command full market value. 6–9 months: 70–80% of market value. 3–6 months: 40–60%. Under 3 months: very hard to sell, not worth our time. Check the expiration date on each box before reaching out.
Must not be Medicare-sourced: If your CGM supplies were paid for by Medicare or Medicaid, they legally cannot be resold. This is a federal rule, not something we make up. Private insurance or cash-pay supplies are fine to resell.
Must be stored properly: CGM sensors should be stored at room temperature, away from heat and light. Sensors that have been stored in a hot garage or car (especially in Arizona summer) may have degraded and won't pass quality checks.
Why People Sell CGM Supplies
The most common situations we see:
- Switched systems: Your endo switched you from Dexcom G6 to G7, but you had a 3-month supply of G6 already.
- Insurance changed: New plan covers a different brand, leaving you with a stockpile of the old one.
- No longer diabetic or no longer needing CGM: Lifestyle changes, medication changes, or remission can mean your CGM is no longer necessary.
- Loved one passed away: Family member was on CGM, and there are sealed supplies left over.
- Over-ordered: Got a 90-day supply but ended up switching before using it all.
- Type 1 athletes: Some T1D athletes cycle through CGM brands based on what works for their activity level and accumulate surplus.
How to Sell Your CGM Supplies to StripValue

💡 Pro tip: If you're switching CGM systems, reach out to us before you transition. That way your G6 supplies sell while they still have plenty of time before expiration — maximizing what you get.
CGM vs. Test Strips — Which Is Worth More?
CGM sensors are generally worth significantly more per unit than traditional test strips. A single Dexcom G7 sensor lasts 10 days and replaces potentially hundreds of finger-stick tests. The resale market reflects this — CGM sensors are in higher demand and command higher prices per box than traditional blood glucose test strips.
That said, we buy both. If you have a mix of CGM supplies and traditional test strips, send us the full list and we'll quote everything together.
