THE COMPANY THAT MADE CUSTOMERS PAY TO ENTER THE STORE
Imagine walking into a supermarket.
Before you can buy anything, someone tells you:
“You need to pay us first.”
Sounds like a terrible retail strategy.
Costco turned it into one of the most powerful parts of its business model.
YOU DON'T PAY FOR THE PRODUCT FIRST
At Costco, the customer pays for a membership.
Only then can they regularly shop at the warehouse.
That creates something unusual in retail:
THE CUSTOMER PAYS COSTCO BEFORE COSTCO MAKES THE SALE.
And that changes the economics.
BUT WHY WOULD CUSTOMERS AGREE?
Because Costco makes a simple promise:
LOW PRICES.
The membership fee is supposed to be justified by the savings customers can get from shopping there.
So the customer is effectively making a calculation:
“Will I save more money at Costco than this membership costs?”
If the answer is yes...
the membership feels like an investment rather than an extra cost.
NOW LOOK AT IT FROM COSTCO'S SIDE
The membership fee creates a second revenue stream.
Costco makes money from:
PRODUCT SALES
MEMBERSHIP FEES
That matters because Costco deliberately operates with relatively low merchandise margins.
In fiscal 2025, Costco reported about $269.9 billion in net sales and $5.3 billion in membership fees.
The membership model helps support the company's low-price strategy.
THE REAL MAGIC IS RECURRING REVENUE
A normal retailer has to convince you to buy something every time you walk into the store.
Costco already has a relationship with you.
You paid for the membership.
Now you have an incentive to use it.
The more you shop:
MORE VALUE FROM MEMBERSHIP
↓
MORE REASON TO RENEW
↓
MORE SHOPPING AT COSTCO
↓
MORE SALES FOR COSTCO
It's a very different relationship from ordinary retail.
MEMBERSHIP ALSO CHANGES CUSTOMER BEHAVIOR
Imagine you've already paid for a Costco membership.
Where are you more likely to shop for:
→ groceries
→ household products
→ electronics
→ furniture
→ bulk supplies
You have already paid the entry cost.
So Costco has a built-in reason for you to keep coming back.
THEN COSTCO ADDS ANOTHER TRICK
Costco doesn't try to offer an enormous number of versions of everything.
It often carries a relatively limited selection compared with traditional supermarkets.
Why?
Because buying larger quantities from fewer products can create enormous purchasing power.
Instead of negotiating separately for dozens of similar products...
Costco can concentrate demand.
HIGH VOLUME → STRONGER PURCHASING POWER → LOWER COSTS
THE WAREHOUSE LOOK IS PART OF IT TOO
Costco doesn't look like a luxury supermarket.
Products can remain in shipping boxes.
The stores are large warehouses.
Displays are relatively simple.
The company doesn't spend heavily trying to make every aisle feel like a premium shopping environment.
The message is essentially:
“We're saving money on the shopping experience so we can save money on the products.”
AND THE MEMBERSHIP FEE CREATES A PSYCHOLOGICAL LOOP
You pay for membership.
↓
You want to get your money's worth.
↓
You shop there more often.
↓
You discover more products.
↓
You spend more.
↓
You feel the membership is worthwhile.
↓
You renew.
The fee isn't simply a source of revenue.
It can also become a reason to keep shopping.
THE BUSINESS MODEL IS ALMOST BACKWARDS
Traditional retail:
Get customer → sell product → earn money
Costco:
Get member → collect membership fee → sell products at very low margins → encourage repeat shopping → renew membership
That changes what Costco can optimize for.
Instead of trying to maximize the margin on every individual product...
it can focus heavily on:
PRICE + VOLUME + MEMBERSHIP RETENTION.
THAT'S WHY THE “ENTRY FEE” WORKS
Costco isn't really charging people to walk through the door.
It's charging for access to its pricing model.
The customer pays for the privilege of shopping there.
Costco then has to make that privilege feel valuable enough that the customer renews year after year.
And that's the important part:
The membership only works if customers believe they're getting more value back than they pay for.
SIMPLE IDEA
A membership fee can look like a barrier.
But if the fee creates enough value, it can become a reason for customers to stay loyal.
Costco didn't just ask:
“How much can we charge for this product?”
It built a model around:
“How much value can we give members while still making the entire system profitable?”
MAACAT PERSPECTIVE
The unusual part of Costco isn't that customers pay before shopping.
It's that Costco turned the customer into a member.
That small change creates:
recurring revenue + loyalty + repeat shopping + predictable demand.
Sometimes the smartest way to make a customer buy more...
is to first give them a reason to come back.
