Costco's ordered code of ethics: law, members, employees, suppliers, then shareholders
Source
When this applies
when deciding the explicit priority order among competing stakeholders (customers, employees, partners, investors) for an organization
The takeaway
Rank stakeholders explicitly and put investor returns last in the stated order; then design the organization to achieve returns as a downstream consequence of satisfying the earlier priorities.
Why it works
By stating explicitly that shareholders are served last, and only as a result of serving the other stakeholders well, the company commits every operational decision to this hierarchy, which in turn reliably produces the shareholder returns at the end.
One level up
If you consistently serve upstream priorities (customers, workforce, partners) well, financial returns become a natural byproduct rather than a goal pursued directly.
Where it stops holding
This stops working when a business lacks the unit economics or scale to actually generate enough return while fully prioritizing the other stakeholders — the ordering only works if the model's economics allow it.
Detail
hierarchy:
- Obey the law
- Take care of our members/customers
- Take care of our employees
- Respect our suppliers
- Reward our shareholders (as the resulting outcome, not a direct goal)
rationale: Jim Sinegal: 'if we do these four things throughout our organization... then will achieve our ultimate goal, which is to reward our shareholders.'
In their words
If we do these four things throughout our organization, and again, those four things are obey the law, take care of our members, take care of our employees, respect our suppliers in that order, then will achieve our ultimate goal, which is to reward our shareholders.
Scale economies shared with customers (Nick Sleep's framing, applied to Costco)

When this applies
when deciding whether to capture scale-driven cost advantages as profit or reinvest them into customer value to build a compounding moat
The takeaway
When you have scale economies, reinvesting the savings into lower prices for customers (rather than into margin) compounds the advantage into a flywheel competitors structurally can't match without sacrificing their own margin or growth model.
Why it works
Volume gives negotiating leverage with suppliers for the lowest honest price; instead of keeping the savings as margin, the company minimizes its own overhead and passes savings to customers, which grows volume further and repeats the cycle.
One level up
Durable competitive advantage often comes from the discipline to forgo available short-term profit in favor of compounding structural advantage.
Where it stops holding
This stops working when a business lacks sufficient scale to negotiate meaningfully better supplier terms, or when its own overhead can't realistically be driven low enough to pass savings on.
Detail
procedure:
- Use volume to negotiate the lowest honest supplier price (not the lowest possible, exploitative price).
- Minimize internal overhead to the leanest sustainable level.
- Mark up goods by the smallest possible margin to pass savings to customers.
- Repeat: more value brings more members/volume, which brings better supplier terms.
benchmarks: {"Costco_overhead":"~10-11%","Amazon_overhead":"~30%"}
rationale: Nick Sleep's phrase 'scale economies shared with customers' captures why this flywheel, once spinning, is hard for a competitor with a different incentive structure (extracting margin) to replicate.
In their words
They get more members, they get better deals from suppliers.
Pay employees well to buy down turnover and shrinkage

Acquired — Costco (May 2, 2026) · at 31:21 ▸
When this applies
when deciding whether to minimize labor cost per hour or optimize for total labor cost including turnover and loss
The takeaway
Optimizing for the lowest unit cost of an input (wages) can raise your true total cost; optimize instead for total system cost including retention and trust effects.
Why it works
Higher wages and good benefits increase per-employee cost but drastically cut turnover, training cost, and theft, because loyal employees feel invested in the company's success.
One level up
The cheapest-looking input price is not the same as the lowest total cost once second-order effects (turnover, morale, integrity) are included.
Where it stops holding
This stops working when turnover and theft are already structurally low for other reasons, or when the business can't capture the retention/trust benefits (e.g. very short-tenure, gig-style labor markets).
Detail
rule: Pay well above industry average to drive down turnover and shrinkage, and treat this as a profit lever, not just a cost center.
threshold: 7% annual turnover at Costco vs ~20% typical retail; 0.15% shrinkage of sales.
rationale: Lower turnover cuts hiring/training costs; loyal employees reduce theft; internal promotion builds institutional knowledge (36% of US employees have 10+ years tenure).
In their words
So, obviously, the trade-off of this is for Fedmart at the time and straight through to Costco today. This creates meaningfully higher per employee labor costs for the company
Cap markup as a hard, enforced rule to build irreversible trust
Source
Acquired — Costco (May 2, 2026) · at 1:20:50 ▸ · at 1:23:49 ▸
When this applies
when deciding whether to extract easy incremental margin from a customer base that trusts you
The takeaway
Commit to an inviolable, simple rule limiting your own short-term extraction, because consistent restraint compounds into trust that is worth more long-term than the marginal profit foregone.
Why it works
A hard cap on markup (never exceeded even when easy margin is available) builds compounding trust because customers and suppliers learn the pricing is never going to be gamed, which increases volume and loyalty more than the extra margin would have been worth.
One level up
The discipline to never 'cheat a little' even once preserves an asset (trust) that, once broken, cannot be rebuilt by future good behavior alone.
Where it stops holding
This stops working when your customers/suppliers can't observe or don't care about pricing consistency, or when margin trust isn't a meaningful part of your value proposition.
Detail
rule: Never mark up any product more than 14% above supplier cost (15% max for the house brand).
threshold: 14% hard cap; target 11% average gross margin; 89% of supplier cost reductions passed to members.
rationale: Jim Sinegal: raising prices is like heroin — easy and addictive once you start, and breaks the trust relationship with members and suppliers that the whole business model depends on.
In their words
You could raise the price of a bottle of ketchup to $1.03 instead of $1, and no one would know. Raising prices just 3% would add 50% to our pre-tax income. Why not do it? It's like heroin. You do it a little bit and you want a little more.
Intelligent loss of sales: standardize on fewer SKUs/sizes even if it costs some marginal customers
Source
When this applies
when deciding how much variety/customization to offer versus how much operational simplicity to gain by standardizing
The takeaway
Deliberately accept a known, bounded loss of some marginal customers/sales in exchange for a disproportionate gain in operational simplicity and the compounding benefits that follow from it.
Why it works
Offering only the highest-volume size/variant forgoes a small fraction of marginal sales, but drastically reduces SKU count, which compounds into faster inventory turns, simpler logistics, lower overhead, and the ability to negotiate harder with fewer suppliers.
One level up
The right trade-offs are chosen by asking which small, intentional sacrifice unlocks outsized structural advantages elsewhere in the system.
Where it stops holding
This stops working when customers abandon you entirely rather than accepting the narrower selection, i.e., when the forgone segment is large enough to threaten the core business, not just marginal.
Detail
rule: Deliberately forgo a known slice of sales (e.g., smaller package sizes) in order to minimize SKU count and reap the downstream operational benefits.
threshold: Costco today: ~3,800 SKUs versus Walmart's 100,000–150,000.
rationale: Saul Price's own example: carrying only the 8-ounce can of lubricating oil, foregoing sales to customers who only wanted a 3-ounce can, because the SKU reduction was worth more than those lost sales.
In their words
Saul developed this kind of principle back in Fedmart that he called the intelligent loss of sales
