Yes, you can sell sealed, unused, in-date Dexcom G6 supplies. A vetted local buyback can be a convenient route for cash, where items are inspected and paid for on the spot. A specialist online buyer that handles shipping compliance is the next best choice. If you mail anything, confirm the buyer’s shipping instructions before you seal the box.
TL;DR:
- Buyers commonly reject opened, expired, damaged, or recalled items; transmitters and receivers may qualify in like new condition, depending on the buyer.
- Offers improve with longer remaining shelf life and full lots, while clear photos of dates and lot numbers can support quotes and later disputes.
- Some previously owned electronic devices with lithium batteries must travel by domestic surface transportation and may need exterior restricted device markings when mailed.
- For safer payment, wait until cash or a bank transfer has cleared before handing over supplies, and keep photos, messages, receipts, and serial numbers.

Which Dexcom G6 supplies can you sell?
Buyers care about whether the item is sealed, unused, and still in date. If your boxes meet those three tests, you have something to sell.
The Dexcom G6 is a regulated medical device. The FDA’s 510(k) documentation classifies the G6 family as Class II continuous glucose monitoring devices made up of a sensor, a transmitter and an app. That is why buyers ask for clear proof of condition and origin.
Here is what we and most buyers look at:
- Sealed sensor boxes: factory seal intact, nothing removed, no tampering.
- Transmitters and receivers: accepted by many buyers when sealed or in like-new condition.
- Expiration date: printed on the box. Short-dated boxes still sell, but for less.
- Lot numbers and serials: buyers record them to confirm the product is not recalled.
- Quantity: the number of full boxes you have, not loose parts.
- Proof of ownership: some buyers ask for an original receipt or pharmacy label.
Items that are commonly turned down include opened or used sensors, expired boxes, damaged packaging, and recalled or damaged devices. If a box has been opened, even once, treat it as used.

How do you prepare your supplies before selling?
A little prep speeds up the offer and protects your payout. Spend a little time on this before you contact anyone.
- Pull out every box and group them by product: sensors, transmitters, receivers.
- Read the expiration date on each box and write it down. Our expiration checklist shows where to find it.
- Record the lot number and any serial number next to each date.
- Count full boxes and note the total quantity.
- Photograph each unopened box so the date and lot number are readable, plus any transmitters or receivers.
- Keep original boxes, inserts and accessories together. Do not repackage anything unless the buyer asks you to.
- Decide how you want to sell: in person for speed, or by mail if you are outside the area.
Pro Tip: Photograph the boxes in good light before you do anything else. Clear photos of the lot number and date help a buyer prepare a quote, and they protect you if a price is questioned later.
If you want a deeper walkthrough on confirming lots, see our page on verifying lots before you sell. In short, selling locally is usually faster and lower risk, while mailing can reach more buyers but adds shipping steps and waiting time.
Where can you find buyers for Dexcom G6 supplies?
You have several realistic routes. Pick one that matches what you care about most: speed, safety or price.
- Local same-day buyback: you bring sealed boxes, they are inspected, and you are paid on the spot. This is the lowest-risk way to turn supplies into cash quickly, and it avoids shipping entirely.
- Specialist online buyers: these buyers accept sealed supplies by mail and usually manage the shipping rules for you. Offers can be competitive, but you wait for the package to arrive and be verified.
- Private groups and classifieds: diabetes communities and online listings can work, but you carry the vetting and scam risk yourself. Verify who you are dealing with before sharing details.
- Donation: if cash is not the goal, nonprofits and community programs sometimes accept sealed, in-date supplies. Ask first, since many will not take devices.
If you are in the Orlando area, our local service is built for the first option. Our guide to getting cash for unused diabetic supplies explains the process step by step.
What are the shipping and safety rules if you mail items?
Transmitters and receivers contain lithium batteries, and that changes how they can travel. A USPS Postal Bulletin update explains that pre-owned, damaged or defective electronic devices with lithium batteries must go by domestic surface transportation only, and the package may need “Restricted Electronic Device” and “Surface Transportation Only” markings.
Some pre-owned electronic devices with lithium batteries must be mailed by surface transportation only, and the package may need restricted-device markings on the exterior. That is the single rule most sellers miss.
Practical points to keep in mind:
- Never mail a damaged, defective or recalled battery or device.
- Professional buyers usually handle the labeling and ground-only requirements, as practitioner guidance on USPS lithium rules notes.
- If you ship yourself, follow the buyer’s written instructions exactly.
- Use a trackable service and keep the receipt.
- Confirm the shipping method and labeling before you pack, not after.
For the full rules, USPS publishes its mailable hazardous materials guidance in Postal Explorer.
What determines how much your Dexcom G6 supplies are worth?
Value comes down to a few plain factors, and you can influence most of them.
- Expiration date: more shelf life means a higher offer.
- Sealed versus opened: only sealed boxes carry real resale value.
- Quantity: a full lot of boxes is easier to price and often earns a better per-unit rate than a single box.
- Demand: what buyers want changes over time, so offers can move.
Our Dexcom G6 resale value page shows sample price ranges and what affects them. To see what a mixed pile of leftovers might fetch, try our guide to assessing leftover supply value.
To get a stronger offer, group full boxes together, show clear photos, and describe condition honestly. If you overstate condition, expect the payout to be adjusted after inspection, so accuracy works in your favor.
How do you get paid safely and avoid scams?
Most bad outcomes come from rushing. A few habits keep you protected.
- Prefer cash in hand at an in-person meeting, or a verified bank transfer you can see has cleared.
- Confirm any electronic payment is complete before you hand over the items.
- Be wary of overpayment offers and refund schemes. A buyer who “accidentally” sends too much and asks for the difference back is running a scam.
- Never ship before payment clears, unless you are using a buyer you have vetted.
- Meet in a public, well-lit place, or use the buyer’s established meet-up process. Bring a friend if you feel unsure.
- Keep records: photos, messages, receipts and serial numbers.
Pro Tip: Save your conversation and a photo of the boxes in one folder before the meetup. If anything is disputed later, you have the whole story in one place.
On taxes, IRS Publication 502 does not give specific guidance on reselling surplus medical supplies. Generally, selling personal property for less than you paid is not treated as taxable income, but a tax professional can confirm how that applies to you.

FAQ
Where can I sell my Dexcom G6?
You can sell sealed, in-date supplies to a local same-day buyback, a specialist online buyer, or through vetted private groups. A local buyer can be convenient because inspection and payment happen at the same meeting. Mailed sales take longer because of shipping and verification.
Is the Dexcom G6 a regulated device?
Yes. FDA 510(k) documents classify the Dexcom G6 system as a Class II continuous glucose monitoring device made up of a sensor, transmitter and app. This is why buyers ask for lot numbers and proof the product is sealed and unused.
What is the cash price for Dexcom G6 supplies?
Offers depend on expiration date, whether boxes are sealed, and how many you have. Longer shelf life and full lots bring better rates. Our Dexcom G6 resale value page lists sample ranges.
Can I mail my Dexcom G6 transmitter?
Often yes, but with conditions. Transmitters contain lithium batteries, so USPS surface-only rules and restricted-device markings can apply. Follow your buyer’s shipping instructions and never mail a damaged or recalled device.
Can I sell Dexcom G7 sensors too?
We also buy unused G7 sensors. Our page on selling Dexcom G7 sensors explains what we accept and how the process works.
