How Much Are CGM Sensors Worth: Real Cash Prices by Brand

How much are CGM sensors worth in cash depends on brand, model, and whether the factory seal is intact. Sealed Dexcom G6 3-packs pay up to $150. Dexcom G7 15-day sensors fetch up to $60 each. FreeStyle Libre 3 sensors pay up to $30 each, and Omnipod 5 pods can bring up to $150 per pod. Text us photos and we send back a real number the same day.

CGM sensor prices by brand

These are top payouts for sealed, non-expired sensors in original retail packaging with 12 or more months to expiration. A short expiration date or any condition issue will lower the offer.

• Dexcom G6 sensor 3-pack: up to $150
• Omnipod 5 Starter Kit: up to $300
• Omnipod 5 pod (single): up to $150 each
• Dexcom G6 transmitter kit: up to $80
• Dexcom G7 15-day sensor: up to $60 each

Dexcom G7 10-day sensors are worth up to $40 each. FreeStyle Libre 3, Libre 2, and Libre 14-day sensors all land at up to $30 each. FreeStyle Libre readers (14-day and 3 models) are worth up to $30 each as well. Medtronic insulin pumps sit in their own tier at up to $500 depending on the model and accessories. For a full side-by-side with test strips too, the full price guide has everything in one place.

What qualifies a CGM sensor for the top payout

Four things determine whether a sensor gets the full quote. First is the factory seal. An opened sensor box is worth nothing to any reputable buyer because nobody downstream will accept it. Second is the expiration date. Sensors with 12 or more months until expiration get the highest offer. Inside six months, the quote drops noticeably. Inside three months, most buyers will pass.

Third is original retail packaging. The box needs to look the way it came from the pharmacy. No repackaging, nothing transferred to a bag, nothing wrapped in tape. Fourth is the pharmacy label issue. If your box has a relabeling sticker pasted over the brand name from an insurance delivery, that takes it out entirely. The FDA's guidance on CGM devices is clear that device integrity depends on keeping the original manufacturer packaging and labeling intact. That is why buyers care about the seal and the label — it is not arbitrary.

Why Dexcom and Omnipod pay more than other brands

The payout difference between brands comes down to downstream demand, not quality. Dexcom G6 and G7 sensors are among the most prescribed CGM systems in the country. That broad install base means buyers can move them reliably. Omnipod 5 pods and starter kits sit at the top because the system is expensive at retail and patients who are prescribed it often end up with more pods than they use in a month.

FreeStyle Libre sensors bring a solid number too, but the per-sensor price is lower because Libre sensors are cheaper at retail than Dexcom. The resale market reflects retail pricing. A Dexcom G6 3-pack retails for several hundred dollars. A FreeStyle Libre 3 sensor retails for a fraction of that. The cash we pay tracks with where those market prices land.

For test strips, the same logic holds. Dexcom sensors and Omnipod pods will almost always out-earn a box of test strips on a per-item basis. If you have both CGM supplies and test strips to sell, we look at everything together and give you one payout for the lot.

Why so many CGM sensors end up going unused

The most common reason is a doctor switch. A client of ours a few years back kept going back to his doctor because his Libre 3 sensors wouldn't stay on his arm. After enough visits, the doctor moved him to Dexcom. He had a full stockpile of sealed Libre 3 boxes sitting in his cabinet — sensors that were perfect, just a brand he could no longer use. We paid him $700 cash for the lot at one meetup.

Insurance and prescriptions don't reset the moment a doctor changes your CGM system. You end up with a cabinet full of the old brand before the new one even arrives. Those boxes are real money, but only before the expiration clock runs out. The full breakdown of how CGM sensor expiration affects value walks through the shelf-life timeline for each brand and what to expect if your boxes are getting close.

Overprescription is the other common driver. The American medical supply system tends to ship more than most patients use. If you are getting a monthly supply but only using three-quarters of it, that other quarter stacks up fast. A year of mild overprescription can turn into a drawer full of sensors worth several hundred dollars. Also see how FreeStyle Libre sensors are valued and sold if Libre is your main brand.

Local buyers vs mailing in your CGM sensors

Mail-in CGM buybacks exist, and for someone in a rural area without a local option they make sense. For most Wasatch Front sellers, they are a worse deal. Mail-in programs send a quote first, then re-inspect when the package arrives. That second-look quote is often lower than the first. The worst case is not a lowball offer. The worst case is shipping your sensors and getting nothing back at all.

Local meetups work because the inspection happens before any money moves. The price you get over text is the price you receive in cash when we meet. Our on-site deduction rate is rare across 1,500+ transactions — what we say in the text is what we hand over. Our repeat rate runs about 95%. If someone sells to us once, they almost always come back. That tracks with the American Diabetes Association's data on CGM adoption, which shows that most CGM users eventually switch systems at least once. Leftover sensors from a brand switch are not unusual. A local buyer who prices honestly is the faster, cleaner way to handle them.

How to get paid for your CGM sensors

The process is short on purpose:

1. Text us a photo of the front of each sensor box.
2. Add a photo of the expiration date on each box.
3. Tell us roughly how many of each brand you have.

During business hours (Mon–Sat 10am–7pm, Sun 12–3pm MT) we respond in under 30 minutes with a real number. If the price works, we pick a public spot near you — usually a Starbucks or a Smith's parking lot. Most meetups run about five minutes. We look at the boxes, confirm what the photos showed, and pay right there in cash, Venmo, Cash App, or Zelle.

If you have a large stockpile or can't easily drive to a meetup, we come to you. We cover roughly a 50-mile radius from Salt Lake City, which takes in most of the Wasatch Front. Y'all don't need to sort through what each box is worth before reaching out. Text photos of everything and we will tell you what qualifies and what the lot is worth.
