Sell Dexcom transmitters for cash — G6 kits up to $85

Direct answer: sealed Dexcom G6 transmitter kits currently pay up to $85 (REF STT-OE-002) or up to $60 (REF STT-OR-001 / STT-OM-001). G7 users don't need transmitters at all, so kits left over after an upgrade are pure surplus — and fully sellable while still in date.

Current transmitter payouts

From our 2026-08-03 offer schedule (rounded to the nearest $5). Columns show time remaining until expiration. Final offer depends on the exact REF/NDC, expiration date and package condition.

Sensor box ≠ transmitter box

G6 sensors and G6 transmitters are separate products with separate REF codes, and mixing them up is one of the most common quote mistakes we see:

• The transmitter kit is a small box containing one transmitter; its REF starts with STT.
• Sensor boxes contain one or three sensors; their REFs use OE/OR/OM codes.

Never use a sensor REF for a transmitter (or vice versa) — the REF guide shows where each code lives on the packaging.

Eligibility checklist

• Factory-sealed kit, unopened, seals intact
• Eligible time remaining before the printed expiration date

Frequently asked questions

How much is an unused Dexcom G6 transmitter worth?

Sealed G6 transmitter kits with REF STT-OE-002 pay up to $85. Kits with REF STT-OR-001 or STT-OM-001 pay up to $60. The REF is printed on the box near the barcode.

Why don't you buy G7 transmitters?

There's no such thing — Dexcom G7 integrated the transmitter into each disposable sensor. That's exactly why sealed G6 transmitters left over after a G7 upgrade have no future use for the upgrader and are worth selling.

My transmitter box has a prescription pharmacy label on it. Is it still eligible?

Usually yes, as long as the factory seal is intact and the box isn't marked for Medicare/Medicaid use or not for resale. Don't peel pharmacy labels off — tell us about them in your submission and we'll confirm eligibility before you ship.

Does the transmitter battery age even in the box?

Transmitter kits carry an expiration date for a reason, and offers require an eligible amount of time remaining. Submit the printed date exactly as shown and your quote will reflect the correct tier.
