Most mainstream test strip buyback companies do not purchase strips that are already past their expiration date. The buyers who do accept expired strips are a smaller, more specialized group: medical waste and recycling companies, certain research organizations, and occasionally individual buyers on online marketplaces. If your strips are expired, your options are more limited than someone selling unexpired surplus, but they do exist.
Why Most Buyback Companies Won’t Take Expired Strips
The dozens of buyback websites you’ll find online, like Diabetics Trust and More Cash for Test Strips, resell the strips they purchase to people who need affordable diabetes supplies. Because those end users rely on accurate readings to make insulin dosing decisions, buyback companies only want strips that are still within their expiration window. The FDA specifically warns consumers to check expiration dates before using any test strip, and strips past their date can produce unreliable blood glucose readings. That accuracy concern is why the resale market strongly favors unexpired product.
Most buyback sites require at least several months of remaining shelf life before they’ll make an offer. When you request a quote, you’ll typically enter the brand name, box size, and expiration date. If the date has passed, the system either returns a zero-dollar offer or rejects the submission entirely. For example, one major buyer currently lists $0.00 payouts for several OneTouch strip products, likely reflecting low demand or oversupply for those specific items even when unexpired.
Who Actually Buys Expired Strips
Three types of buyers may be interested in strips past their printed date.
Medical waste and recycling companies specialize in repurposing medical supplies. They purchase expired test strips to extract valuable materials and recycle components. Payouts from these buyers are typically much lower than what you’d get for unexpired strips, but they offer a way to recover some value rather than simply throwing the supplies away.
Research organizations sometimes purchase expired strips to study how expiration affects accuracy and reliability. Universities and product testing labs may want batches of expired strips for controlled experiments. This isn’t a consistent or high-volume market, but it exists. You’re more likely to find these opportunities through direct outreach to diabetes research programs than through a standard buyback website.
Individual buyers on platforms like eBay, Facebook Marketplace, and Craigslist occasionally purchase expired strips at steep discounts. Some buyers are uninsured or underinsured people with diabetes who can’t afford retail prices and are willing to accept slightly reduced accuracy. Others may be resellers speculating that the strips still work well enough to move. Selling directly to individuals generally brings unpredictable pricing and carries more risk on both sides of the transaction.
What Expired Strips Are Worth
If your strips are unexpired and sealed, buyback companies pay meaningful amounts. Dexcom G6 sensor packs (quantity of 3) fetch $120 to $170 depending on packaging. Freestyle Libre sensors sell for around $40 to $42. Freestyle Lite test strips in 100-count retail boxes go for about $30. These prices apply to sealed, undamaged, unexpired product.
Expired strips, by contrast, bring a fraction of those amounts. Recycling companies might pay a few dollars per box, and individual buyers on secondary marketplaces typically expect discounts of 50% or more compared to unexpired pricing. The further past the expiration date, the less anyone will pay. Strips that expired a month ago are a much easier sell than strips that expired a year ago.
Selling Strips That Haven’t Expired Yet
If your strips are still within their expiration window, selling to a buyback company is straightforward. You visit the company’s website, enter your strip details, and receive an instant price quote. If you accept, they send a free prepaid shipping label. You pack the boxes, ship them, and receive payment within one to two business days of the company receiving your package. It’s legal to resell unused test strips in the United States, and many people with diabetes do exactly this when they switch meters, change medications, or end up with more supplies than they need.
Boxes need to be factory-sealed and undamaged. The FDA recommends that anyone buying or using resold strips inspect the packaging for signs of tampering or alteration. Opened vials, torn seals, or boxes with missing labels will be rejected by legitimate buyers.
Avoiding Scams When Selling
The test strip resale market attracts some bad actors. The HHS Office of Inspector General warns about fraud schemes targeting people with diabetes, particularly those involving Medicare. Be cautious of any buyer who asks for your Medicare number, insurance details, or personal health information. A legitimate strip buyer needs to know the brand, quantity, and expiration date. They don’t need your Social Security number or insurance card.
Red flags include buyers who offer prices that seem too good to be true, request payment information before you’ve shipped anything, or pressure you to act quickly. Stick to established buyback companies with verifiable business addresses, customer reviews, and clear payment terms. If you’re selling on a peer-to-peer platform, use the site’s built-in payment protection rather than accepting wire transfers or gift cards.
What to Do With Strips Nobody Will Buy
If your expired strips are too far past their date for anyone to purchase, you still have options beyond the trash can. Some charitable organizations accept expired medical supplies for distribution in areas where any testing capability is better than none. Local pharmacies occasionally run take-back programs for unused diabetes supplies. You can also contact your local household hazardous waste facility, though test strips are generally safe for regular disposal since they don’t contain significant hazardous materials once used or unused.
