1. Item Count vs. Cart Contents
Did your receipt say “3 toilet paper packs” but you only have 2 in your cart? → You were overcharged.
Did you buy a 40-pack of water but the cashier scanned it as two 20-packs? → You paid double.
→ The checker counts large or bulky items to verify accuracy.
2. Receipt Codes: The “Digital Fingerprint”
The alphanumeric codes at the top/bottom of your receipt are unique to your transaction and register.
If there’s a dispute later, Costco can instantly pull up your full purchase record—no guesswork.
3. Supervisor Initials on Big-Ticket Items
Purchases over $300–$500 (like electronics, jewelry, or appliances) require supervisor approval at checkout.
Those initials on your receipt? Proof that a second set of eyes verified the price and authorization.
→ This protects you from accidental $1,000 mistakes.
❌ What They’re NOT Doing
Not searching for shoplifters: If they suspected theft, they’d involve security—not just glance at your receipt.
Not checking membership: Your card was scanned at entry.
Not judging your purchases: That 96-roll toilet paper haul? They’ve seen it all—and they don’t care!
💡 Why Other Stores Don’t Do This (But Costco Does)
Most retailers prioritize speed over accuracy—you’re on your own once you leave the register.
But Costco’s model is different:
Membership-based: You’re a valued member, not just a customer.
High-ticket items: A single scanning error could cost you hundreds.
Customer-first ethos: Founder Jim Sinegal famously said: “If you want to make money, take care of your customers.”
The receipt check is a small ritual with a big promise:
“We stand behind every transaction.”
❤️ A Note to Shoppers: How to Make It Easier
Keep your receipt visible (don’t crumple it!).
Pause at the exit—don’t rush through like you’re guilty.
Smile and say thanks—those checkers are doing an often-thanked job!
And if they do catch an error? Costco will refund you on the spot—no receipt needed.
💛 Final Thought
That receipt check isn’t a barrier.
It’s a handshake—Costco’s way of saying:
“We’ve got your back. Always.”
So next time you hear “Receipt, please!”, don’t sigh.
Appreciate it.
Because in a world of impersonal retail, Costco still treats you like family—one receipt at a time.
