What your Costco receipt color really means (and other questions answered)

This is why Costco really checks your receipts

We’re all used to the routine. We go to Costco with a set shopping list (and somehow end up buying twice as much stuff), wait on the checkout line while debating if we should opt for that sweet, inexpensive hot dog combo (the answer is almost always yes), and then fork over our receipt to the worker at the door so they can check our stuff before letting us leave. (And maybe there’s a detour to pick up glasses, meds, or tires along the way.)

It’s a tradition for most homeowners and bulk shoppers, but there are a lot of questions about Costco receipts: What do the different colors mean? Do you need Costco receipts for returns? And just why does Costco check receipts anyway? We’re here to answer all your burning questions.

What do the different color Costco receipts mean?

While you might be used to the usual white receipt when you go to Costco, you could end up with yellow, blue, or green receipts, too. What do the different colors mean? Costco enthusiasts have been discussing this for ages, but generally speaking:

  • A white Costco receipt means you went to the main cashier checkout.
  • A green Costco receipt means you made a return.
  • A blue Costco receipt is for self-checkout or the food court kiosk.
  • A yellow Costco receipt is for the food court, optical center, pharmacy, tire center, or photo center.

(And yes. We have gone to Costco and gotten all four colors in one day on occasion.)

Why does Costco check receipts anyway?

Do you ever wonder why Costco checks your receipts at the door? While the most common answer from Costco shoppers is “to prevent theft,” that’s not the whole answer. (And let’s be honest: We all buy so much stuff that if Costco workers were checking every item, we’d be stuck standing there for hours.)

According to the company’s website, it’s to make sure that your items were correctly processed by the cashiers. “It’s our most effective method of maintaining accuracy in inventory control, and it’s also a good way to ensure that our members have been charged properly for their purchases,” the website states.

Costco employees elaborated to Business Insider that they’re looking for a code on the receipt that changes every day to ensure the receipt was printed that day; the item count to check for under or over charges; high-end items (which require a supervisor’s initials); and that large items like tissues and water (aka the stuff you dump underneath the cart to avoid filling the basket too quickly) weren’t overlooked.

Do you need a receipt to return at Costco?

You get home from your shopping trip, unload your bags, and realize you’ve bought the wrong laundry detergent or the shirt you picked up didn’t fit. But by the time you go to return the items, you can’t find your receipt anywhere. Do you really need it?

While it’s helpful to have the receipt handy to speed up the process, it’s not always necessary, according to Costco. The nice thing about a membership-based store is that all of your purchases are linked to your membership, making it easy for store employees to look up your past orders. And if the purchase was made within the last two years, you can look it up and print the receipt yourself using your Costco.com account. (Bear in mind, of course, that while Costco has a pretty liberal return policy, there are exceptions and limitations.)

So there you have it: The next time you’re leaving your local Costco, staring at your receipt, you’ll have all your questions answered.

How to Style a Coffee Table That Feels Collected, Not Cluttered
Plant, Furniture, Table

A well styled coffee table can make your formal living room stand out and should feel intentional, considered and appropriately arranged. The goal is balance, and it should support the room rather than compete with it.

Start with a foundation. Use one or two large books to ground the arrangement. Choose books with substantial covers that reflect the palette of the room, whether neutral or tonal, and complement the space. Stack them rather than spreading them out. This creates structure and gives everything else a place to sit.

Flowers From the Garden: A Summer Centerpiece Method
Flower, Flower Arrangement, Plant

A simple, season led approach to summer florals, built on what is in bloom rather than what is in stock.

There is a particular generosity to summer that no other season offers. The garden is full and the flower markets overflow. The roadside stands begin to set out buckets of zinnias and dahlias by mid June and July. The backyard, once an afterthought, begins to feel like an extension of the home itself. The question is no longer whether to bring flowers into the house, but how often.

The Easiest Way to Set the Table
Cutlery, Fork, Spoon

Have you ever wondered why the fork sits on the left and the knife on the right? Or why Europeans eat “Continental style,” holding the fork in their left hand and the knife in their right, while Americans cut, switch hands, and then eat? It turns out there’s a reason for all of it, and once you understand the history, setting the table suddenly feels far less mysterious. Before beautifully layered place settings and Pinterest-worthy tablescapes, dining was far more practical. Medieval feasts were less about etiquette and more about survival. Plates were often shared, forks were nonexistent, and eating with your hands was the normal standard. Tables were filled with trenchers (pieces of bread used as plates), and the idea of “proper placement” simply didn’t exist.

By the mid-to-late 1800s (around 1860–1870), European dining evolved again as meals began to be served in courses. This shift introduced what became known as the Russian style of dining, where utensils were laid out intentionally and used from the outside in. The fork stayed in the left hand, the knife in the right, and the table itself began to reflect structure, rhythm, and order. This approach eventually became the “Continental style” still used across much of Europe today.
