Aftermarket pricing
A Socratic walk-through of aftermarket pricing — reasoned out one step at a time, not lectured.
The question we started with
THE QUESTION #Why does a company sell the printer cheaply and charge dearly for the ink?
A home printer can be bought for less than the price of two sets of the cartridges it takes. Measured by the millilitre, that ink is one of the more expensive liquids most households buy.
The obvious reading is that the seller is fleecing us on the ink. But that only relocates the puzzle: if ink is so profitable, why not also charge properly for the printer? A firm that can extract a fortune on the refill should be able to extract something on the machine too. Selling the durable good at or near cost is a deliberate sacrifice. What is it buying?
Reasoning it through
REASONING #Notice first that the buyer is not really purchasing a printer. They are purchasing printed pages, over several years. The machine and the cartridges are two components of one long purchase, and the firm can put the price anywhere across them. The total is what matters to its revenue; the split is a free variable.
So what does the firm gain by loading the price onto the back end?
Begin with the moment of choice. At the shop, the buyer compares printers on the number on the shelf. The lifetime cost of ink is real but distant, hard to compute, and depends on knowing how much you will print — so it weighs far less than the front price does. Shifting money from the visible number to the less visible stream makes the offer look better without making it cheaper. Economists call this a shrouded attribute, and it is studied precisely because it survives competition: a rival who advertises the honest total tends to lose to one advertising a low headline.
Now go further, to what happens after the sale. Once the printer is on the desk, the buyer's situation has changed completely. The machine only accepts the maker's cartridges, and it is already paid for. When the ink runs out, the choice is not "this ink or a cheaper ink" but "this ink or throw away a working printer". Even a large markup is smaller than the cost of switching. The buyer, who had every option before the purchase, has very few after it.
That transformation is the point of the cheap machine. It is not a loss but the cost of installing a customer somewhere the seller has power it did not have during the sale. The device is the investment, the consumable the return.
Two more benefits follow. The scheme sorts customers by intensity of use without the firm having to ask: someone who prints constantly pays a great deal, someone who prints twice a year almost nothing, each roughly in proportion to how much they value the thing. And the low entry price puts machines into the hands of buyers who would never have paid full cost up front, enlarging the installed base all this revenue depends on.
But this works only while one condition holds, and it is worth stating sharply: someone else must not be able to sell the refill. If a third party can make compatible cartridges, they will compete the aftermarket price down toward cost — and the firm has given away the machine for nothing. Everything a manufacturer does to defend the aftermarket flows from this. Patents on the cartridge, authentication chips that reject unrecognised refills, firmware updates that disable third-party ink, subscription schemes, warranty terms: none of these are incidental. They are the structural requirement of the pricing model, made visible.
The analogy
THE ANALOGY #Think of a toll bridge built at the developer's own expense and opened free to the town on the far side. People move there because getting in costs nothing. Once they have bought houses, the developer starts charging to cross — and they pay, because moving away costs far more than the toll. The bridge was never a gift; it was the mechanism for creating a population that has to use it. And the scheme survives exactly as long as no one else may build a second bridge.
A household on the far side of the bridge is locked in for a decade, whereas a printer is a small object with a finite life, so the lock-in is bounded and buyers do defect at replacement time — which is why manufacturers must keep re-earning the position with each new machine rather than holding it permanently.
Clarifying the model
THE MODEL #Two corrections, one of them to the story everyone tells.
The first concerns Gillette. The model is universally called razor-and-blades, on the strength of an anecdote in which King Gillette gave away razors to sell blades. Legal-historical research into the actual pricing — Randal Picker's work is the standard reference — found the opposite. During the patent period from 1904 to 1921, Gillette sold its razors at a high price and did not give them away; the cheap-handle strategy took hold only after the patent expired and competitors drove handle prices down. The model is real and widespread. Its founding legend is largely backwards.
The second concerns how well it works. It is not a reliable licence to print money, and it fails in identifiable ways. Where compatible or remanufactured consumables are legal and available, the aftermarket margin erodes and the discounted hardware becomes a straightforward loss. Where buyers are sophisticated and repeat-purchasing — businesses computing cost per page — the shrouding does not work, and firms sell them machines priced closer to cost-plus with cheaper toner. And aggressive defence of the aftermarket has repeatedly drawn antitrust and consumer-protection attention, so the lock-in has a legal ceiling as well as a technical one.
It is also worth separating two mechanisms that often get merged. Price discrimination — heavy users paying more — would be a coherent reason for metered pricing even with fully informed buyers. Lock-in and shrouding are about the buyer's weakened position and imperfect attention. Real cases mix them, and how much of a markup is one rather than the other is hard to establish from outside the firm.
A picture of it
THE PICTURE #How to readS1 is the strategy, and the four arrows leaving it point at the conditions it depends on — read "derives" as derived from, so the strategy only pays where all four hold. The three elements below are candidate products, and what matters is which arrows they have. The inkjet printer reaches three conditions and is the sturdiest modern case; the console reaches defended fitting through licensing rather than a physical part. The razor after its patent expired reaches only repeat purchase — and that missing arrow to defended fitting is exactly why anyone could sell a blade that fitted.
What became clearer
WHAT CLEARED #The cheap printer is not a discount and the dear ink is not simple gouging. They are two halves of one price, split so that the visible part attracts the sale and the invisible part collects the money afterwards, once the buyer's options have narrowed to almost none. The firm pays for the machine in order to own the position that follows. And its dependence on keeping rivals out of the aftermarket explains the whole apparatus of chips, patents and firmware — as well as why the model collapses wherever that defence fails.

| Lock-in | the condition of a buyer for whom leaving costs more than staying, arising after purchase rather than before. |
| Shrouded attribute | a real cost not salient at the moment of choice, so competition does not compete it away. |
| Price discrimination | charging different effective prices to different buyers, here by metering use through the consumable. |
