How to Sell Unused Dexcom Sensors: Payouts and Pickup

How to sell unused Dexcom sensors is a straightforward process once you know the pricing tiers and what the box needs to look like. Dexcom G6 and G7 sensors pay more per unit than most test strip brands, and the surplus is more common than people expect. Insurance overships. Doctors switch patients between CGM models. The supplies pile up, still sealed, still dated right, while the new sensor order arrives.

What unused Dexcom G6 and G7 sensors actually pay

These are the current payouts for sealed, undamaged Dexcom sensor boxes at the standard dating tier. Dexcom G6 (3-pack): up to $120. Dexcom G7 15-day (single sensor box): up to $50. Dexcom G7 (single sensor box): up to $35. Those are the published rates for boxes with 7 or more months before expiration.

Dexcom transmitters and receivers are a separate item. Text a photo to (617) 702-2220 and we will quote from the specific model and condition. The rates vary too much by model to publish a flat number.

Any other Dexcom configurations not listed above (different pack sizes, kits, accessories) — a photo gets you a current number. CGM sensor prices move more than test strip prices do, so the photo quote is always the most accurate number we can give.

The dating rule that determines your offer

Dexcom sensors need 7 or more months before expiration for the full published rate. Shorter dating does not automatically mean rejection, but the offer scales down. Under 3 months, the numbers typically do not work.

The expiration date is printed on the side or bottom of the outer box, usually in MM/YYYY format. If the box contains multiple sensor pouches, the date on the outer carton is the one that controls the offer. The guide on reading supply dating covers how to find and interpret expiration dates on both strip and sensor boxes.

What the box needs to look like

Sealed factory packaging. Original seal intact, no torn perforations, no opened flaps. The box should look exactly as it came from the pharmacy.

Box damage bigger than a quarter disqualifies. Damage smaller than a quarter may mean a deduction rather than a flat rejection. A dented corner or a crease you are not sure about. Text a photo and we will give you a direct answer.

Pharmacy label on the box? Leave it there. Peeling it off yourself almost always damages the cardboard and reduces the offer. We remove and shred labels at the office. The post on the legality of selling diabetic supplies also covers the label question and what the process looks like when a box has one.

Why people end up with extra Dexcom sensors

Insurance does not move on your schedule. A doctor switches someone from G6 to G7, or from Dexcom to FreeStyle Libre, and the new order arrives. The previous order for the old model is already in transit or already delivered. Sometimes two fills land before anyone updates the plan. You are on G7 now with six G6 boxes you will never open.

The American Diabetes Association's overview of CGM options reflects how frequently the monitoring landscape shifts. New models, expanded insurance coverage for specific devices, and treatment plan changes all create the same result: sealed supplies from the old setup that nobody is going to use.

A surplus can also build gradually. Insurance ships on its own cadence. If you are using fewer sensors per month than the plan assumes (say, extending wear time or managing with fewer sensors during a lower-monitoring stretch), the boxes accumulate. A year in, there are enough to warrant a call.

The post on selling supplies after a CGM switch goes into more detail on why the surplus happens and what typically qualifies after a brand or model change.

Local pickup versus mailing your sensors in

Once you ship to a mail-in buyer, you are on their timeline. The number you saw on their website is not the number you will see on the check. Boxes get re-graded after they arrive. The process can take up to 3 weeks from the time you put the sensors in the mail. Once they have the box in hand, you have no recourse if the revised price is not what you expected. Most mail-in buyers will not return the supplies if you disagree with the deduction.

One customer sold Dexcom supplies every few months as his surplus built up. He tried mailing them in once. After 3 weeks and a revised offer once the company had the boxes, he switched to local pickup. He still comes back every few months. Same supplies, cash in hand the same day, no waiting to find out the number changed.

The breakdown of local versus mail-in buyback covers the full comparison. Short version: local is faster, the quoted price is binding, and you see the cash before the sensors leave your hand.

How the pickup process works

Text a photo to (617) 702-2220. Front of the box, expiration date visible in the shot. Multiple boxes, a group photo is fine and we can sort it from there. During business hours (Mon–Sat 9am–6pm, Sun 11am–4pm) you will typically have a quote back within about 60 minutes.

The quote from your photo is the number you walk away with. We do not re-grade at pickup. Whatever we quote off the photo is what you get paid when the sensors leave your hand.

Local pickup is the specialty. Worcester County and 25 miles out, cash in your hand the same day. Core Worcester zone usually runs same-day. Outer towns we schedule when we have stops in the area. Cash, Cash App, or Venmo the day of pickup, your call.

We have been doing this since 2019 and have completed 2,000+ pickups. For the full list of current payouts across all sensor and strip brands, the full price guide has every published rate. The FDA's information on continuous glucose monitors is useful context on the regulatory side of CGM devices.

The one time not to sell

If you are on a different CGM now but still reach for the old Dexcom sensors occasionally as a backup, do not sell those. Supplies that fill a real monitoring gap are not surplus.

We only want what you genuinely do not need. Take care of your health first. If you are between brands, off a refill cycle, or sitting on a supply you cannot realistically use before expiration, that is the inventory we are here for. Not a situation where someone sells today and regrets it when a sensor fails and there is no fallback.

Genuine surplus, sealed, dated right? Text us a photo. You will have a number the same morning. Text (617) 702-2220.
