If you switched from one continuous glucose monitor to another, you may be holding sealed Dexcom boxes you will never use. They are valuable, and selling them is a smart way to recover some of their cost. Sealed sensors rarely lose their usefulness just because your prescription changed.
How much your Dexcom sensors are worth depends on the model, the packaging, and the expiration date. Test Strip Buyers buys both G6 and G7 supplies and posts pricing so you can see your range before you ship. Knowing what drives the number lets you set realistic expectations.
This guide explains what drives Dexcom value, how G6 and G7 compare, and how to get an exact quote for your boxes.
What Decides How Much Your Dexcom Sensors Are Worth
Several things set the value of a Dexcom box: the model, whether it is a sensor or a receiver, the count, and how much time is left before expiration. Sensors generally carry more value than receivers. Each part of the system is judged on its own merits.
Condition and packaging matter too. A sealed, undamaged box in its original packaging with a long expiration date sits at the top of the range.
Demand also plays a role. Because Dexcom is widely prescribed and expensive at retail, sealed sensors stay in steady demand. That demand is what keeps sealed sensors valuable on the resale market.
Dexcom G6 Value: Sensors, Transmitters, and Receivers
The G6 system splits into parts, and each is valued differently. Sealed G6 sensor boxes are the core of most sales, while transmitters and receivers carry their own separate values. Knowing which parts you have helps you estimate the total.
Box codes and whether a box is retail or supplied through a pharmacy or DME channel can affect both eligibility and price. The same product can be quoted differently based on these details.
If you have a mix of G6 items, each is assessed on its own, so a full box of sensors and a spare receiver are priced separately.
Dexcom G7 Value and Why It Often Differs
The G7 combines the sensor and transmitter into one unit, so its boxes are valued as a single item rather than separate parts. Newer systems in high demand often hold strong value. The all-in-one design also makes the boxes simple to assess.
As with G6, the count, expiration date, and packaging channel shape the final number. A sealed G7 box with a long date is worth more than one nearing expiration.
Because Dexcom continues to update the G7 line, checking current pricing is the only way to know your exact range. You can see current Dexcom prices by item.
Why Two Dexcom Boxes Can Be Worth Different Amounts
It is common for two seemingly identical Dexcom boxes to be quoted differently. The usual reasons are the expiration date and the difference between retail and DME or pharmacy packaging. Small differences on the label can mean a real difference in the offer.
Reference codes printed on the box can also signal which channel a box came from, which affects whether and how it qualifies. This is why a quote based on your actual boxes beats a rough estimate.
Expired sensors cannot be purchased, and boxes close to expiring are valued lower, so timing matters.
