Direct answer: we buy sealed Tandem infusion sets (AutoSoft XC, AutoSoft 90, AutoSoft 30 and TruSteel, any REF), priced by expiration date. Pick them in the quote tool like any other product. t:slim and Mobi cartridges are not currently accepted.
What we buy
- AutoSoft XC infusion set — sealed 10-pack, any REF
- AutoSoft 90 infusion set — sealed 10-pack, any REF
- AutoSoft 30 infusion set — sealed 10-pack, any REF
- TruSteel infusion set — sealed 10-pack, any REF
- t:slim X2 and Mobi cartridges — not currently accepted
Boxes need at least 6 months before the expiration date; 9 or more earns the top offer. One rate covers every REF within a line: tubing and cannula length do not change the offer.
How to pick the right listing
- Find the set name on the front of the box: AutoSoft XC, AutoSoft 90, AutoSoft 30 or TruSteel. Any REF within that line uses the same listing.
- Check the expiration date on the end panel and choose the matching range in the quote tool.
- Count sealed boxes, not individual sets. Each 10-pack is one unit.
Eligibility rules
- Factory-sealed, unopened boxes with intact seals
- In date, with enough shelf life for resale — longer dating always pays more
- Purchased privately or out of pocket; no Medicare/Medicaid-labeled boxes, nothing marked "Not for Resale"
- Clean packaging (damage lowers the offer)
Pump switchers: bundle the whole drawer
Most Tandem sellers just moved to OmniPod, Mobi or a different system — which usually means CGM surplus in the same cabinet. Dexcom and Libre boxes have posted rates, and everything ships under one free label with one same-day payment.
How selling works
- Add your boxes in the quote tool: pick the set, the expiration range and the count.
- Approve the firm offer we send the same day.
- Ship free with a prepaid shipping label by text or email.
- Get paid on arrival after inspection — Zelle, Venmo, Cash App or PayPal.
Frequently asked questions
Which Tandem supplies can I sell?
Sealed 10-packs of AutoSoft XC, AutoSoft 90, AutoSoft 30 and TruSteel infusion sets, any REF, with at least 6 months to expiration. t:slim X2 and Mobi cartridges are not currently accepted.
Why is the price the same for every REF?
Within one line, tubing and cannula length do not change what a sealed 10-pack is worth to the pharmacies we supply, so one rate covers every REF. The expiration date is what moves the offer.
I switched from t:slim to OmniPod or Mobi. Can I sell my leftover supplies?
Pump switches are the top reason we see Tandem surplus. Sealed infusion sets from before your switch are sellable while still in date — and any leftover CGM boxes can go in the same shipment.
What makes a Tandem box ineligible?
Opened or resealed boxes, expired product, Medicare/Medicaid payer labeling and 'Not for Resale' marks. Damaged packaging is still bought, at a reduced offer. Everything else can be added in the quote tool.
Switched pumps? Your sealed Tandem sets have a set price.
Add them in the quote tool, approve the offer, ship free with a prepaid shipping label, and get paid the same day your box is inspected.
