Costco

Traditional retail operates on a fundamental tension: the retailer profits by marking up products, which means the retailer's financial interest is directly opposed to the customer's interest in payin

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.
