Libre 3 vs Libre 3 Plus: Which FreeStyle Libre Sensors Can You Sell?
Share
Quick answer: Only the Plus versions can be sold. A sealed FreeStyle Libre 3 Plus box pays $40 with at least 6 months left before it expires, and a sealed FreeStyle Libre 2 Plus box pays $20 with at least 7 months left. The original Libre 2 and Libre 3 (no "Plus" on the box) are not on our buy list.
What is the difference between Libre 3 and Libre 3 Plus?
They look almost identical, and that is the problem. Both are small, round, one-piece sensors that you wear on the back of your arm and read with your phone. The practical differences:
- Wear time. The original Libre 3 is labeled for 14 days of wear. Libre 3 Plus is labeled for 15 days.
- Where it is headed. Abbott has been moving U.S. users onto the Plus versions of both the Libre 2 and Libre 3, and the Plus sensors are the ones pharmacies are dispensing now.
- Resale value. Because the Plus sensors are the current product, they are the ones with buyer demand. The older non-Plus boxes are not.
The same logic applies to Libre 2 vs Libre 2 Plus: the Plus version is the current 15-day sensor and the one we buy.
How to tell which one you have in five seconds
- Read the product name on the front of the box. A Plus box says FreeStyle Libre 3 Plus (or FreeStyle Libre 2 Plus). If the word "Plus" is not there, it is the original version.
- Check the wear time. The Plus boxes reference 15-day wear. The originals reference 14 days.
- Check the expiration date. It is printed on the side of the box next to the hourglass symbol. You need at least 6 months left for Libre 3 Plus and 7 months for Libre 2 Plus.

What each FreeStyle Libre box is worth

Libre prices are flat: there is no sliding scale by date, as long as the box clears the minimum. That means a Libre 3 Plus box expiring in 7 months and one expiring in 14 months both pay $40. The minimum still matters, though. Once a box drops under 6 months, it can no longer be sold at all, so do not let a stack sit in a drawer.
A stack of Libre boxes adds up fast
Libre sensors often ship two or three months at a time. A 90-day supply of Libre 3 Plus is six boxes, which is $240. Add a seventh box and you clear $250, which qualifies a first-time seller for our $20 new-seller bonus.
What else has to be true
- Factory sealed and unopened. No loose sensors outside the box.
- Bought in the U.S.
- Not funded by Medicare, Medicaid, TRICARE, or the VA. See why government-funded supplies can't be resold.
- In mint condition. Boxes with dents or dings, writing, adhesive residue, crushed corners, torn or half-peeled labels, or water damage are not accepted.
