The Nerf Gun Incident: Sunk Costs, Suppressing Fire and the Glassblower

Have you ever watched a small, entirely avoidable expense reveal itself as a window into how modern spending actually works? I recently received a masterclass, courtesy of a Nerf gun, a glass light shade, and my own stubborn refusal to just buy a new kitchen fixture.

It started on New Year’s Eve, or early New Year’s Day, to be precise. Two of the twenty-something guests had discovered my grandkids’ Nerf gun stash and declared war. Being the mature, wiser person in the room, I had them pinned behind the breakfast bar within minutes. Unfortunately, one of my suppressing shots went high and a glass light shade exploded, raining down on my enemies in what was, objectively, a spectacular conclusion to any firefight.

Then came the financial reckoning.

The fixture was a matte chrome light sculpture, four pendant shades over the breakfast bar, original cost around $2,500. It had required seventeen lighting store visits and more sales assistant input than any human should endure, and had become the undisputed focal point of the kitchen. Now one of the four shades was gone. Here’s where the math gets rather sad. A four-shade fixture missing one shade isn’t worth 75% of its value; aesthetically, emotionally, practically, it’s worth approximately nothing.

The sunk cost of the original $2,500 was now holding the remaining fixture hostage to a single $40 piece of glass. Except that $40 piece of glass didn’t exist anywhere on the open market. Weeks of searching confirmed what I’d suspected: the manufacturer had discontinued the shade entirely. This is the part where I’d normally chalk it up to bad luck, except it’s not bad luck at all.

It’s a business strategy. Make replacement parts easy to source and you’ve sold someone a $40 component; make them impossible to source and you’ve nudged them toward a $2,500 repurchase. The replacement shade you stock costs warehousing, logistics, and eats into a future full-unit sale. The replacement shade you discontinue generates zero cost and, eventually, a repurchase from a consumer who’s already demonstrated they’ll pay the premium.

The really elegant part, and I say this with genuine grudging admiration, is that they’ve correctly identified our sentimentality as a financial liability we’ll absorb on their behalf. That breakfast bar light isn’t just a light. It’s “the” light, the one that works with the splashback tiles and the cabinet handles and the general thesis of the kitchen. Replacing it means reopening every connected decision.

This is price anchoring working in reverse. Normally, anchoring means showing you an expensive option first so a cheaper one feels reasonable. Here, your own sunk emotional investment anchors you to the existing fixture so aggressively that a $325 custom replacement feels like the bargain move. Compared to $2,500, it genuinely is — and the manufacturer created that anchor by discontinuing the $40 part in the first place.

The resolution arrived through a friend’s suggestion: a bespoke replacement from an artisan glassblower, commissioned for $325. On paper, I paid a 700% premium over the component’s original retail value. In practice, I paid to protect a $2,500 asset and avoid a much larger repurchase, which makes the $325 the rational choice…I think.

The artisan glassblower exists precisely because the manufacturer created the gap. Every time a corporation decides that replacement parts are bad for margins, it creates a micro-market for someone with a blowtorch and genuine skill. The planned obsolescence economy and the artisan economy are symbiotic: one manufactures the problem and the other charges a premium to solve it.

The real lesson isn’t “don’t play Nerf guns indoors”, though Suzie made that point with considerable clarity and forcefulness. It’s that the moment you buy something designed to be irreplaceable, you’ve handed a portion of your future financial decisions to whoever manufactured it. They knew that when they priced it. You just didn’t know it yet — thank god for glassblowers is all I have to say.
