Sell Tandem Pump Supplies: Turn Unused Cartridges and Infusion Sets Into Cash

This guide walks you through everything you need to know — what supplies qualify, how much you can expect to earn, and how to get paid fast.

Why People End Up With Extra Tandem Pump Supplies

Life changes quickly for people managing diabetes. You might have switched to a different pump, upgraded your therapy plan, or received more supplies than you needed through insurance. Whatever the reason, unused supplies have value — and throwing them away means throwing away money.

The American Diabetes Association estimates that millions of Americans live with type 1 diabetes and rely on insulin pumps. That means there is always a real need for affordable pump supplies in the community.

Common Reasons Sellers Contact Us

• You switched from Tandem to a different insulin pump brand
• Your doctor changed your infusion set type or cannula length
• A loved one passed away and left behind unopened supplies
• Your insurance over-supplied you and boxes piled up
• You transitioned to an all-in-one system and no longer need separate supplies

Any of these situations can leave you holding boxes of perfectly good, unopened Tandem supplies. Selling them is a smart and simple solution.

What Tandem Pump Supplies Can You Sell?

Not every item qualifies, but many of the most common Tandem accessories do. The key rule is simple: supplies must be unopened, unexpired, and undamaged.

t:slim X2 Cartridges

Tandem's 3mL cartridges are one of the most requested items we receive. If you have boxes that have never been opened and are not within 90 days of expiration, they are likely eligible. View Price List to see current rates.

Infusion Sets

Tandem-compatible infusion sets — including AutoSoft 90, AutoSoft 360, and TruSteel — are in high demand. Sellers often have multiple boxes in different cannula lengths after switching to a different set that works better for them.

Pump Accessories and Supplies

Some additional Tandem-related items may also qualify, such as:

• Unopened pump cases or pouches (manufacturer sealed)
• Compatible CGM supplies used alongside the t:slim X2 (like Dexcom sensors)
• Unused luer lock syringes included in supply kits

If you are unsure whether something qualifies, just reach out. Our team is happy to take a look before you ship anything.

How Much Money Can You Make?

The exact amount depends on the item, quantity, and expiration date. In general, the more boxes you have and the longer they have until expiration, the more you will earn.

Here is a rough idea of what drives your payout:

• Quantity: Selling 10 boxes earns more per box than selling 2
• Expiration date: Supplies with 12+ months remaining pay the most
• Condition: Original sealed packaging is required
• Current demand: Some items are in higher demand than others at any given time

Is It Legal to Sell Unused Insulin Pump Supplies?

This is one of the most common questions we hear, and the answer is yes — with some important details.

Selling unopened, unexpired diabetic supplies that you legally obtained through a prescription is permitted. What is not allowed is selling supplies that have been opened, tampered with, or obtained through fraudulent means.

The FDA provides guidance on the resale of medical devices, and MySurplusRx.com operates in full compliance with applicable state and federal regulations. We only purchase supplies that meet strict quality and safety standards.

It is also worth noting that selling your own legitimately acquired supplies is different from commercial resale. Most individuals selling a few boxes of extras have nothing to worry about.

Frequently Asked Questions

Can I sell Tandem infusion sets if I only have one box?

Yes, we accept sellers with small quantities. Even one or two boxes may be worth selling, especially for in-demand items like AutoSoft 90 sets. The payout may be smaller, but it is still money you would otherwise lose.

How close to expiration can my Tandem supplies be?

We generally require at least 6 months remaining before the expiration date. Supplies with 12 months or more fetch the best prices. If you are unsure, submit a quote request and we will let you know.

Do I need a prescription to sell my supplies?

No. You do not need to provide any medical documentation to sell your unused supplies. We simply need to verify the items are unopened and unexpired.

How long does the whole process take?

From quote to payment, most sellers complete the process in 3 to 5 business days. Shipping time is the biggest variable, but our prepaid labels use Priority Mail, which is fast.

What if my supplies do not qualify?

If your items do not meet our standards, we will let you know right away — before you ship anything. You will never be out any money or time if your supplies do not qualify.
