HOW IT WORKS

Zero Commitment. 100% On-Demand. We only process refills after the USPS scans your empty cylinders. If you never send them back, you’re never charged again. Simple.

  • 📦 Get Your Label ($0)

    Choose your cylinder count and checkout for $0. We’ll email your prepaid return label instantly

  • 📦 Ship When Ready

    Pack your empty cylinders in any box, attach the label, and drop it at to the carrier. No rush, no deadlines.

  • Person scanning a package of c02 with a barcode scanner at a post office counter.

    📦 Scan to Ship

    Once USPS scans your box, your card is billed for the refill and we ship your fresh cylinders the same day!
