What to Do With Extra CGM Supplies, Sensors, and Pods
If you're wondering what to do with extra CGM supplies — a drawer full of Dexcom sensors, FreeStyle Libre boxes, or Omnipod pods you no longer need — the short answer is: sell them before they expire. Sealed, in-date CGM supplies are worth real money, often more than people realize, and in Salt Lake City you can turn them into cash the same day you text us photos.
What actually counts as sellable CGM supplies
The short checklist is the same across all CGM brands. The box needs to be factory-sealed, unexpired (at minimum, a few months of shelf life remaining — ideally 6+), and in its original retail packaging. If those three things are true, you almost certainly have something worth cash.
The most common items we buy are Dexcom G6 sensor 3-packs, Dexcom G7 sensors, FreeStyle Libre 2 and 3 sensors, and Omnipod 5 pods and starter kits. We also buy Dexcom G6 transmitter kits and FreeStyle Libre readers. If you're not sure whether what you have qualifies, just text us a photo of the box and the expiration date — we'll tell you in under 30 minutes whether it's a yes.
What extra CGM supplies are actually worth
CGM supplies tend to pay better than test strips, box for box, because the downstream demand is strong and the retail prices are high. Here are the top payouts we offer for items in the best condition (sealed, 12+ months to expiration, original retail packaging):
- Dexcom G6 sensor 3-pack: up to $150
- Dexcom G6 transmitter kit: up to $80
- Dexcom G7 (15-day) sensor: up to $60 each
- Dexcom G7 (10-day) sensor: up to $40 each
- FreeStyle Libre 3 sensor: up to $30 each
- FreeStyle Libre 2 sensor: up to $30 each
- FreeStyle Libre reader: up to $30
- Omnipod 5 Starter Kit: up to $300
- Omnipod 5 pod (single): up to $150 each
- Medtronic insulin pump: up to $500
Those are top payouts for supplies in the best condition. The real number you get will depend on the expiration date and exactly what you have. Check our full price guide for diabetic supplies for the complete current breakdown by brand.
When your doctor switches your CGM brand
The most common reason people end up with a stockpile of extra CGM supplies is a mid-treatment switch. Doctors move patients between Libre and Dexcom all the time — sometimes for adhesion issues, sometimes because a newer sensor has better accuracy, sometimes just because your coverage changed. When that happens, the boxes you had on hand don't disappear.
One of our clients had been going back to his doctor for months saying his Libre 3 sensors wouldn't stay put on his arm. After enough visits, his doctor moved him over to Dexcom. He brought us his remaining Libre 3 supply — sealed, in-date boxes he'd never use — and we paid him $700 cash for it at a Starbucks in about ten minutes. Insurance and prescriptions don't reset overnight when your treatment changes. Those leftover boxes are real money, and they're on a clock.
The same thing happens with Omnipod. If your doctor moves you to a different pump system or you switch to injections, those unopened pod kits don't stop being valuable just because you're not using them. How fast you get paid is usually the same day you reach out, as long as what you have qualifies.
Why local is usually the better call for CGM supplies
The national mail-in CGM buyback sites — ValueCGM, SellCGM, and similar — are real and they do pay. But for anyone living on the Wasatch Front, mail-in means 1 to 3 weeks of waiting, a re-grade risk after they receive your package, and no recourse if something goes wrong. For someone in Wyoming with no local buyer, that trade-off makes sense. For someone in Sandy who can be at a Starbucks in 12 minutes, it's leaving both time and money on the table.
With a local meetup, the price you're quoted before you drive anywhere is the price you get paid. We check the boxes in front of you. The whole thing takes about five minutes. You walk away with cash, Venmo, Zelle, or Cash App — whatever works for you. There's a real difference between "we'll pay you after we inspect them" and "here's your real number before you leave your house." For CGM supplies especially, where the per-item value is higher, that difference matters more.
We cover the full mail-in vs local comparison in another post, but the short version for CGM supplies is this: local gives you a confirmed price, same-day cash, and no shipping anything you already have in your hands.
A quick four-point check before you text us
Before you reach out, run your boxes through these four points. If all four are a yes, you've almost certainly got something we want.
- The factory seal is intact. The box hasn't been opened. This is the single most important thing. An opened sensor box is a no, no exceptions.
- The expiration date is at least 3 months out. Six months or more is ideal. Closer than three months and the offer drops significantly or disappears.
- No pharmacy label. If there's a paper label from a pharmacy glued over the brand name, we can't take it. That applies to the sensor boxes and to any readers or transmitters.
- Original retail packaging. The box should look like it came off a pharmacy shelf. Generic or repackaged versions of CGM sensors are a hard pass.
If your situation is more complicated than a simple yes/no on those four points — say, you have a mix of in-date and close-to-expiring boxes, or you're not sure what the brand is exactly — text us photos and we'll sort it out fast. We've bought extra diabetic test strips and CGM supplies from more than 1,500 transactions over five years. A mixed bag is something we see all the time.
How the local CGM buyback process works
It's short on purpose. Text us a couple of photos of the boxes, the lot numbers, and the expiration dates. We'll respond with a real number — not a "we'll let you know after we see them in person" line — within 30 minutes during business hours. If the price works for you, we pick a public spot near you (a Starbucks, a Smith's parking lot, wherever is easy), you bring the boxes, we inspect them, and you're paid on the spot.
The most common reaction from first-time sellers is "wait, that's it?" Most meetups run about five minutes. We almost never adjust the quote on-site after we've already sent you a number — what we say in the text is what we hand you in cash. If you can't drive to us (big stockpile, no car, just easier if we come to you), we'll come to you. We've done it plenty of times.

The American Diabetes Association's overview of CGM technology is a good read if you want to understand the clinical side of the devices you're selling. The FDA's continuous glucose monitoring page covers device classification and labeling requirements. And if you want to look up your specific Dexcom model's specs before you text us, Dexcom's website has the full details.
Frequently asked questions
What CGM supplies can I sell for cash?
We buy sealed, unexpired Dexcom G6 and G7 sensors, Dexcom G6 transmitter kits, FreeStyle Libre 2 and 3 sensors and readers, Omnipod 5 pods and starter kits, and Medtronic insulin pumps. The box needs to be factory-sealed with the original retail packaging and at least a few months of shelf life remaining.
How much will I get for extra Dexcom G6 sensors?
For sealed Dexcom G6 sensor 3-packs with 12+ months to expiration and no pharmacy label, we pay up to $150 per box. That's the top rate — the real number depends on the specific expiration date and condition. Text us photos and we'll send a real number back within 30 minutes.
Can I sell FreeStyle Libre 3 sensors for cash?
Yes. We pay up to $30 per sealed FreeStyle Libre 3 sensor. The same rules apply: factory seal must be intact, no pharmacy label, and the expiration date needs to be reasonably far out. FreeStyle Libre 2 sensors and readers also qualify.
What if my CGM sensors expire in less than six months?
Supplies inside six months of expiration get a lower offer. Inside three months, the offer drops significantly or disappears entirely — not because we're trying to lowball you, but because downstream buyers care about shelf life the same way a grocery store does. The expiration math is just real.
Do I need the original prescription to sell CGM supplies?
No. You don't need the prescription, the receipt, or the original purchase documentation. You just need the sealed box in original retail packaging. The one thing that disqualifies a box is a pharmacy label glued over the brand name.
Can I sell Omnipod 5 pods for cash?
Yes. We pay up to $150 per sealed Omnipod 5 pod and up to $300 for an Omnipod 5 Starter Kit, assuming good condition and a strong expiration date. If you're switching pump systems and have a stockpile, those numbers add up fast.
Do you pay more for CGM supplies or test strips?
CGM supplies generally pay more per item than test strips because retail prices are higher. A Dexcom G6 3-pack can pay up to $150 where a 100-count test strip box tops out around $40 for Accu-Chek Aviva Plus. That said, some sellers have many more boxes of test strips than CGM supplies, so total payout depends on what you have.
How long does the whole process take from first text to cash in hand?
Most people wrap up in under 24 hours. You text photos, we respond within 30 minutes during business hours with a real number, you agree or decline, and if it's a yes we find a public meetup spot near you. The meetup itself takes about five minutes.
