How to Sell Extra Diabetic Supplies

Step 1 — Check what you actually have

Before anything else, three things decide whether supplies are sellable:

• The box is factory sealed. Unopened, seal intact. A dented or crushed box is fine — it is worth less, but it is still sellable. An opened one is not.
• It has not expired, and ideally has several months left. Sensors and pods generally need at least three to five months depending on the product; test strips need nine.
• You own them, and they did not come through a government program. Supplies paid for by Medicare or Medicaid cannot be resold, and no legitimate buyer will take them.

Supplies people most often have spare: sensors left over after switching systems, pods that no longer match a new CGM, a prescription that was filled before a change, or an unopened supply of a family member who has passed away or moved on to a different treatment.

Step 2 — Find the code and the expiration date

These two pieces of information are what an accurate quote is built on.

The reference code is on the white label on the side of the box, usually near the barcode. For Dexcom it looks like STP-FT-012 — the last three digits are the part that matters most. Omnipod boxes show compatibility in the top right corner of the front: either Dexcom G6/G7 or Libre 2/3. Libre boxes say 2 Plus or 3 Plus on the front.

The expiration date is printed on the same label. If you have several boxes with different dates, note the earliest one — that is what the lot gets priced on.

Can't find either? Take a photo of the label and text it to 214-898-3911. Reading box labels is a daily job here.

Step 3 — Get a quote

You have three ways to do this, and all of them are free:

• The estimators on this site. Every product page has one. Enter the code, the date and how many you have, and you get a number immediately.
• Message us on Facebook. You will get a price back in the conversation, usually within seconds.
• Text a photo to 214-898-3911.

A word on shopping around: it is worth doing, and most buyers will match or beat a genuine competing offer if you tell them about it. What you should be wary of is anyone who quotes a high number before asking for the code and the dating — that number tends to shrink once the box arrives.

Step 4 — Choose how to hand them over

Local meetup. Anywhere across Dallas-Fort Worth or San Antonio, we come to you and pay cash on the spot. Most people pick a public place — a grocery store car park, a coffee shop, their workplace at lunchtime.

Free mail-in, anywhere in the U.S. You get a prepaid shipping label by text. There is nothing to print: you show a QR code at the post office counter and they print the label for you. How mail-in works covers this in detail.

Step 5 — Pack them properly

This part is simple but worth doing right, because damage in transit costs you money:

• Any box will do — a shipping box, a shoebox, an old Amazon carton.
• Pad around the supplies so nothing rattles. Newspaper, bubble wrap, a towel, plastic grocery bags all work.
• Do not use an envelope or a poly mailer for sensors or pods. They get crushed.
• Tape the box shut properly and put the label on straight, with the barcode flat.

Step 6 — Get paid

Supplies are inspected the day they arrive, and payment goes out the same day by Zelle, Apple Pay, Cash App or PayPal — whichever you prefer. For local meetups you get cash in hand at the meeting.

One thing worth knowing before you ship: mail-in sales are final. If what arrives does not match what was described — a different product, an opened box, less dating than quoted — the offer is revised and paid at the revised amount rather than sent back. That is why the code and the date matter so much at the quote stage.

Common mistakes

• Waiting. Supplies lose value every month. A box with eight months left is worth considerably more than the same box four months from now.
• Guessing the expiration date. Quote off the earliest date in the lot, not the latest.
• Shipping in a padded envelope. Crushed boxes are worth less.
• Assuming damaged means worthless. A dented but sealed box still sells.

How long does it take?

A quote takes a minute. A local meetup can usually happen the same day. Mail-in depends on the post office — typically two to four days in transit, then paid the day it lands.
