Sell Tandem t:slim supplies — cartridges and infusion sets

Direct answer: we buy sealed Tandem t:slim X2 cartridges and infusion sets (AutoSoft 90, AutoSoft 30, TruSteel and related lines). Tandem supplies are quoted individually — send the product name, count, expiration date and a couple of clear photos, and you'll have a firm number the same day.

What to include in your submission

• Product name exactly as printed (e.g., "AutoSoft 90, 23″ tubing, 6mm cannula, 10 sets")
• Count per box and number of boxes
• Expiration date from each box
• Photos — front panel and the barcode/date panel; our photo checklist takes 60 seconds

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, undamaged packaging

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

1. Text photos of your boxes or list them in the quote form.
2. Approve the firm offer we send the same day.
3. Ship free with a prepaid UPS label by text or email.
4. Get paid on arrival after inspection — Zelle, Venmo, Cash App or PayPal.

Frequently asked questions

Which Tandem supplies can I sell?

Sealed t:slim X2 cartridge boxes and unopened infusion set boxes (such as AutoSoft 90, AutoSoft 30 and TruSteel) are quotable. Submit the exact product name, count, expiration date and a photo of the box panels for a firm offer.

Why don't you list flat prices for Tandem supplies?

Tandem packaging spans more variants than CGM boxes — set type, cannula length, tubing length and box count all change the value. Individual quoting gets you an accurate number instead of a misleading range.

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 cartridges and 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, 'Not for Resale' marks, and damaged packaging. Everything else: send the details and we'll quote it.
