What decision this helps you make: Whether to sell cheap-device-plus-profitable-consumable, and how to protect the consumable that pays for it all.

What this topic is

The razor-and-blade model sells a durable device cheap — even at a loss — and makes its profit on the consumables the device requires: razors and blades, printers and ink, coffee machines and pods. The device is the hook; the refills are the business.

Why it matters

It explains why so many products are strangely cheap up front and strangely expensive to keep running. Get the device into a customer's life at a loss, and a stream of high-margin refills follows — for years.

Who should learn it

Anyone selling a product with a recurring consumable, refill, or attachment — and anyone puzzled by cheap printers with outrageously priced ink.

What you will understand

  • See how a device sold at a loss becomes hugely profitable
  • Understand why the profit lives in the consumable
  • Know what makes the model work — control of the refill
  • Spot where it breaks (cheap third-party refills)

Prerequisites

Common misconception

"They must lose money selling that printer/console so cheap." They lose money on the device on purpose — and make it back many times over on the ink, pods, or games. The cheap device is bait for a profitable, recurring consumable.
