Dexcom launched the G7 15-Day system in the United States in December 2025. If you have unopened, unexpired G7 15-Day or original G7 10-Day sensors that you lawfully own and no longer need, TestStrip Buyback USA can provide an estimated offer, a free prepaid UPS label, and same-day payment after your shipment is received and inspected.
Current pricing snapshot: eligible G7 15-Day boxes may receive up to $55–$60 each, depending on the REF code, expiration date, and box condition. Final payment is confirmed after inspection.
G7 vs G7 15-Day — how to tell them apart
- Check the product name. The extended-wear version says “Dexcom G7 15 Day.” The original version is labeled “Dexcom G7.”
- Check the REF code. The REF code on the side or back of the sealed box determines the exact pricing tier.
- Wear time. 15-Day lasts 15 days + 12-hour grace. Original lasts 10 days + 12-hour grace.

- Box condition. Factory seals, readable labels, and clean packaging are required for the quoted tier.
