Questions people ask first
What's actually inside the box?
What if I order the wrong version?
Tell us before it ships and we'll swap it at no cost. After it ships, you can return or exchange any sealed, unopened box within 30 days. If the mistake was ours, we cover the return label.
Why is this cheaper than my pharmacy?
These are sealed, unused boxes that people no longer needed, like after a device switch or an over-supply. We buy them from individuals, check every box, and sell below retail cash price. We're an independent reseller, not a pharmacy or an authorized distributor, and we don't bill insurance.
How do I know it's authentic?
Every box is checked for product identity, an intact factory seal, its expiration date, and active recalls, and it's photographed before it ships.
Can I reorder this easily next month?
Yes. Your account keeps your past orders so you can buy the same thing again. No subscription required.
Who is Spare?
Spare is run by Humble Medical Supply in Casa Grande, Arizona. We've spent years in the diabetes supply business, and we started Spare so people paying out of pocket can get sealed supplies at a fair price. Real people answer at (888) 604-0655, Mon–Fri, 9am–5pm ET.
