you may have noticed that it's a little different.

- Costco is not engineered for a quick shopping trip.

It is exactly the opposite.

- [Narrator] This is the economics of Costco.

- It's not a grocery store.

It's not a small corner store.

It's huge, it's cavernous.

The ceiling is high.

Goods are literally stacked on pallets up to the,

almost the ceiling.

That's all part of the model and the experience.

- I got a Costco hall.

The first think we got is a five dozen of eggs.

Then we've got salmon...

- [Narrator] Unlike most stores, there are no aisle signs

or in store maps to help direct shoppers.

Instead aisles are simply numbered.

What's more Costco, constantly moves some

of its products and cycles in new products.

So what gives?

Why are Costco stores designed this way

and how has it helped the company grow

into the retail behemoth that it is today?

- Costco is a big fan of using treasure hunt retail

psychology to draw you in, which is basically having items

on the shelf that are at a like wow price

because there's such a good discount

or they're just really interesting

and they're not gonna be there forever.

- [Narrator] The big idea behind Costco's

treasure hunt strategy is that by encouraging customers

to explore and ensuring that there's always a new batch

of interesting deals, customers end up shopping longer

and buying more products.

- [Woman] Today, I went to Costco thinking I was just gonna

get a few items, but I ended up with the whole entire cart.

- When you go into the store, it doesn't feel the same

as the last time you were there.

And so you have a sense of urgency about purchasing

and also just a sense of wanting to come back,

right and check out what's going on.

If it was the same, every time you might not come as often.

- [Narrator] Today, Costco is one of the world's largest

retailers boasting over 803 locations and 275,000 employees.

- Costco was part of sort of this early warehouse club

concept which was really about, instead of like

go to the store buy a single item,

come to the store, pay membership

and maybe you're a small business

and we'll offer you wholesale prices,

basically lower prices.

- [Narrator] Most members pay an annual fee of $60

for the basic plan.

The customers can upgrade to the executive membership

which is more perks for $120 a year.

Membership dues are also how Costco makes most of its money.

- I think Costco's management's main goal

is always this ethos of, can we offer more exciting items

at a better price to keep memberships growing?

The model is make money on the membership,

sell things as cheaply as possible.

They can't just raise the price on something

to increase the profit that's against the internal code.

And so that also includes things like let's save money

in how much time we spend putting products on shelves.

So that's part of the reason why you see these pallets

of goods stacked up to the ceiling is there's not a lot

of time spent taking apart those pallets,

putting each individual product on the shelf.

If they eliminate that there's a little bit

of labor savings, there's some time savings

because they're just putting all that stuff out on a pallet

and you take it.

- [Narrator] Costco says that an average item

in the store is only marked up 11% compared to the 25

to 50% often seen in retail.

This commitment to low prices hasn't just kept customers

loyal, it has also helps spread the brand.

- There's a psychology to finding a deal

that's very satisfying for people

and people enjoy the product selection at Costco.

They have very skilled merchants that usually

have been employed there for a very long time

and really know what a Costco customer likely would want.

And they're good at getting good prices on those products.

- I got premier protein flavor vanilla.

- And that sort of creates a certain frenzy

around finding those things.

- I got the Kirkland brand microwave popcorn.

I got two packs of bottled water.

- [Narrator] Most retailers might assume

that shoppers want more choices, not less.

- They sell a limited number of items.

So that means they have to be pretty precise.

They think about like giving space to a product

in their store differently than a Walmart would.

And if that product doesn't sell

like it's out of there, it's very cutthroat.

If you're a product on the shelf

you have to earn your place.

- [Narrator] The average Costco warehouse

stock's about 3,700 products at any given time.

Less than 1/10 of most supermarkets, 40 to 50,000 items.

But even though Costco stocks fewer items

the items they do stock have a reputation.

- I see you've notice me rolling up the sleeves

on my new Kirkland signature quarters

that my mother got me for the holidays.

- Kirkland is Costco's you know, private label brand.

It's their store brand.

It's a brand that when they wanna offer something

at a certain price they don't feel a manufacturer supplier

can do it.

They build it themselves

- [Narrator] Since it was launched in 1995

the in-house brand has built a reputation

for quality and low prices on everyday items.

Today. Kirkland products make up a quarter

of Costco's $166 billion in annual sales.

- But when you talk to customers,

I think they generally feel that it doesn't necessarily

need to be fancy because they've already bought

into this Costco pitch which is, this is high quality

and it's a lower price and you don't need

to be afraid of it.

- [Narrator] That customer loyalty helped Costco

remain strong during the pandemic.

- Costco is certainly a model that has not only

survived the pandemic but has really thrived

in the pandemic.

- [Narrator] Despite the increased popularity

of online shopping Costco has leaned into its strategy

of driving members to it stores.

- It's really interesting to me because for years,

people have questioned Costco.

You know, Amazon is gonna get you.

You got to get bigger online and that really hasn't played

out yet.

They've said explicitly, we prefer people to come

into the store and shop.

We want impulse buys.

We want people to come in and see what we have and buy more.

We work better that way and it's cheaper.
