How to Sell Test Strips by Mail (Step by Step)

The short answer: To sell test strips by mail, list your sealed boxes on a mail-in buyer's kit form, ship them with the free prepaid label the buyer sends you, and get paid once the box arrives. At Cash For Test Strips USA, most kits get a prepaid USPS label and QR code on the screen as soon as the form is saved, and you are paid the day after your box arrives. We buy sealed Accu-Chek, Contour and FreeStyle test strips from all 50 states.

That is the whole process. The rest of this page walks through each step, what we buy, and the questions to ask any mail-in buyer before you ship.

Who this is for

You have sealed boxes of test strips you are not going to use. Maybe you moved to a sensor, your plan switched brands, or you are clearing out a family member's closet. There is no buyer near you, or you would rather not meet a stranger in a parking lot. Mail-in is built for you: you never leave home except to drop off a box.

How to sell test strips by mail in 5 steps

Step 1: Fill in the mail-in kit form

Go to the mail-in kit form. It is two screens and takes a few minutes:

1. Your items. Pick the brand and box for each item and the condition of each box. You see your price as you go.
2. Checkout. Your contact details, the address you are shipping from, and how you want to be paid.

There is no minimum and no account to create. Your kit number and a private link are all you need. One box or a hundred, the form is the same.

Want to see what we pay before you start? Our mail-in price list shows the most we pay per sealed box for every item with a posted price. The kit form holds your prices for 30 days.

Step 2: Get your free prepaid USPS label

Most kits get a prepaid USPS shipping label and a QR code right on the screen the moment the form is saved. If we need to check anything first, we text you instead. Either way, shipping to us is free.

You also get a text, usually within a minute. Reply there any time with a question about your kit, and our team picks it up.

Step 3: Pack and ship

• Keep every box sealed and in its original packaging. Opened boxes cannot be bought.
• Put the boxes in a sturdy outer shipping box with padding so they do not slide around.
• Print the label and tape it on. No printer? Show the QR code at any Post Office and they print it for you.
• Drop it off and keep your receipt.

Step 4: Pick the right box condition

Every box is graded Mint, Dinged or Damaged, and the grade affects the price. You pick the grade for each box on the form. Our box conditions page shows photos of each one so you can match your boxes.

Not sure? Pick the closer one. A dinged box marked mint is simply paid at the dinged price when it arrives, and nothing is held against you for it.

Step 5: Get paid the day after your box arrives

You are paid the day after your box arrives, by the method you picked on the form: Zelle, Venmo, Cash App, ACH or check.

You can follow your kit the whole way on our track my kit page. Enter your kit number and the last four digits of your phone, and your kit page shows the label, the tracking, when the box arrived and when you were paid. It updates on its own.

How to compare mail-in test strip buyers

There are several mail-in buyers. Some are great. Before you ship to anyone, including us, ask these questions. A real buyer answers all of them in writing, quickly.

1. Who are you, and where does my box go? Look for a business name, a phone number a person answers, and a real shipping address. Your prepaid label shows exactly where the box is going. Ours goes to Cash For Test Strips USA in Latham, New York.

2. Can I see your prices before I ship? Some buyers only quote after the box arrives. You have the most leverage before your box leaves home. Look for a posted price list or a firm number for your exact boxes.

3. Who pays for shipping? A good mail-in buyer sends a prepaid label. You should not pay postage to sell.

4. When and how do I get paid? Ask for a specific day, not "soon." Ask which payment methods they use and whether you pick.

5. What happens if the offer changes after my box arrives? Every buyer has a rule for this. Read it before you ship, not after. Ours is in our Terms.

6. Can I track my box and my payment? A tracking number shows the box moving. A kit or order page shows what happened after it arrived.

7. Do you need my bank login or an upfront fee? The answer should be no. Payment apps like Zelle or Venmo only need your phone, email or username. Walk away from any buyer who asks for a password or a fee to "release" your payment.

Mail-in or a local buyer?

Mail-in works from anywhere in the US. If you would rather hand your boxes over in person for cash the same day, use our local buyer directory to find a buyer near your ZIP code. Selling a large lot? See our bulk page; large lots get a per-lot quote.
