Costco

Costco waited seven years to raise its membership fee in 2024 - the longest gap on record - then nudged it $5. That restraint isn't generosity. On ~$5B of near-pure-margin fee income, the math punishes any hike that scares members off.

Costco pays warehouse clerks up to $31.90/hr and stocks fewer than 4,000 items where a supermarket carries 30,000. These look like two unrelated virtues. They are one machine - and each pillar would collapse without the other.

Everyone says Costco loses money on every hot dog. Its own CFO won't confirm it, and its CEO says the in-house factory turned a profit even at $1.50. The dog isn't bleaking cash - it's making a $60 membership fee feel free.

Costco's two Asian bets look identical and aren't. Korea is a 30-year market opened one store at a time; China is a wholly-owned sprint that has already lapped it - and Costco is moving its Korean staff east to prove which one was really the training ground.

Costco renews 92.3% of its members a year and pulls in $5.3 billion in fees that fund the low prices that keep them. Add Kirkland Signature — an estimated $86B brand you can buy nowhere else — and the trap closes on itself.

Most retailers' private labels are the cheap shelf you ignore. Kirkland is roughly the high-20s percent of Costco's net sales — a brand bigger than most public companies — and the moat isn't the label. It's what Costco does to a national brand that won't lower its price.

Costco's famous ~14% markup ceiling appears in no SEC filing - it's an internal rule. But the constraint isn't generosity. It forces the membership fee to carry the profit, which forces low prices to be self-reinforcing rather than discretionary.

The legend says Costco's co-founder told Craig Jelinek to change nothing in 2011. The record shows something less romantic and more durable: a two-year board runway, a formal compensation vote, and a successor who chose continuity in his own words. Revenue still went from $99B to $242.3B.
