Places That Buy Diabetic Test Strips and How They Compare

The places that buy diabetic test strips fall into three categories: local cash buyers, national mail-in companies, and online resale platforms. All three take sealed, non-expired boxes from major brands. What you get paid, and when you get it, varies enough that it is worth knowing the difference before you commit to one.

Local cash buyers: confirmed price, same-day cash

A local buyer is usually a small operation running out of a specific city. We cover Salt Lake City and the Wasatch Front, roughly 50 miles in any direction. The process is short: text a couple of photos of your boxes and expiration dates, get a real number back before you drive anywhere, pick a public spot to meet, hand over the boxes, and walk away with cash or a payment app transfer. For most sellers in Salt Lake, West Valley, Sandy, or Draper, the whole thing wraps up the same day.

We have done over 1,500 transactions across the Wasatch Front in the five years we have been operating. The average meetup takes about five minutes. We almost never adjust the quoted price at the meetup — what we text you is what you get in hand. That predictability is why first-time sellers almost always come back. Our repeat rate sits at around 95%. On pricing, sealed boxes from top brands can be worth real money: an Accu-Chek Aviva Plus 100ct box in good shape with 12 or more months left is worth up to $40, and a Dexcom G6 sensor 3-pack can go up to $150. The full price guide has a brand-by-brand breakdown.

National mail-in buyers: wider reach, longer wait

National mail-in buyers operate through websites. You fill out a form, get a prepaid shipping label, pack up your strips, and send them off. Payment arrives one to three weeks later, usually by check, PayPal, or direct deposit. These companies have been around longer than most local buyers and some have a genuine track record with fair pricing.

The downside worth naming: there is a gap between when you ship and when you get paid, and some mail-in buyers have a practice of adjusting the quoted offer after they receive your supplies. The worst case is not a lowball offer after inspection. It is silence. A client of ours used to ship his extras to a national site every month until one of his larger shipments disappeared into the system and he never got paid at all. He sells local-only now.

Online marketplaces: higher ceiling, much more friction

eBay and Craigslist are technically on the table for sealed test strips, and sometimes the per-box prices available there beat what a buyback service pays. The friction is real, though. On eBay you deal with listing fees, varying demand by brand, and the occasional buyer dispute. On Craigslist you are coordinating with strangers and arranging logistics yourself. For someone with one or two boxes, that work almost never pays off. For someone sitting on a large stockpile and willing to put in the time, the economics can occasionally make sense.

Worth knowing: the FDA classifies blood glucose monitoring supplies as medical devices, and both eBay and Facebook Marketplace have policies around medical supply listings that can get your account flagged depending on how you describe the items. Factor that in before you start building listings.

What makes any buyer worth your time

Whatever option you go with, the buyers worth dealing with share a few things. They give you a real number before you hand over or ship anything. They do not re-grade on arrival unless there is a genuine condition issue you did not disclose up front. They pay on a consistent schedule. And they will tell you directly when something does not qualify instead of accepting it and quietly adjusting the price later. Our guide to spotting a legit test strip buyer walks through the full checklist.

One useful outside resource: the American Diabetes Association's guide to blood glucose testing explains why accurate readings depend on strips being sealed and in date. That same requirement is why reputable buyers care so much about the factory seal and the expiration date. Strips that do not meet those standards should not be resold, and any buyer telling you otherwise is worth avoiding.

What no reputable buyer will accept

Generic store brands like ReliOn and Walmart Equate are a hard sell across the board. The meters themselves are inexpensive, which means there is limited downstream demand for those strips. A few buyers will make a small offer, but most will pass. Before you reach out to anyone, it is worth knowing which brands actually move. The full guide to which test strips are worth the most covers that by brand.

Which option fits your situation

For most people on the Wasatch Front with even a single box to sell, local is the practical choice. Same-day cash, confirmed price before you hand anything over, no shipping label, no waiting. For someone in a rural market where the nearest local buyer is two hours away, a mail-in company with transparent upfront pricing is a reasonable trade for the wait. The online marketplace route makes sense only if you have a large inventory, patience for the process, and time to manage listings.

For anyone in Salt Lake, West Valley, Sandy, Provo, Ogden, or anywhere within about 50 miles of SLC, text us a couple photos and we will send back a real number within 30 minutes during business hours. No runaround. No shipping anything anywhere to find out what happens.
