I spent twenty-six years on one warehouse floor outside Phoenix: the registers, the returns counter, the membership desk, two winters in the bakery and nine years running the front end. This is what I'd tell you at every counter, written down in large print.

Nothing ships, and there is no account to make.
A woman came up to my returns counter one Monday with her receipt in one hand and her phone in the other. She'd paid about ninety dollars for an air fryer the week before. On Saturday she saw the same one on a pallet with a new sign, about seventy dollars.
She thought she had to return it, still in the box, and buy it again at the new price. So she'd driven over with it in her trunk.
I told her to leave it in the trunk. She got about twenty dollars back in under two minutes.
That's the price adjustment, and almost nobody at my counter knew about it until somebody told them. I'm Wanda. I started on the registers in 1998, worked returns, the membership desk and the bakery, and retired in 2024 as a front-end supervisor, when my knees voted for me. I don't speak for Costco. Costco doesn't pay me and has never seen a page of this book. It's what I saw from behind the counter, in plain words.
I watched every one of these come through my register or back across my counter.
One price adjustment on an air fryer paid for most of this book.

At the time I'm writing this, Costco's policy is that if the price of something you bought goes down within 30 days, you can get the difference back. That includes an item that goes on Instant Savings after you bought it.
Go to the counter at the front where they do returns and memberships. Bring your receipt, or your membership card so they can look it up. Leave the item at home. Then say: "Hi, I bought this on [the date] and the price has gone down. Can I get a price adjustment, please?"
Costco adjusts to its own lower price. It won't match another store's sale. I keep every receipt over about fifty dollars in a kitchen drawer for a month, and I glance at those signs every time I'm in.
That's one page out of 182, all in large print.
Each one starts with something I saw on the floor and ends with a short checklist you can read standing in your kitchen with the envelope in your hand.

I'm Wanda. I started on the registers outside Phoenix in 1998, moved to the returns counter, then the membership desk, helped in the bakery for two winters, and spent my last nine years as a front-end supervisor. My husband Dale and I still do one big run every other Saturday.
I love the place, and I still push a cart through those doors twice a month. The warehouse is built to get you to grab one more thing on the way to the register. I watched it happen at my register for twenty-six years.
I don't name my warehouse or the people I worked with, and I don't speak for Costco. Every skip in this book comes with the reason.
Most of the members at my counter had been coming for years, and they still didn't know about the price adjustment, the Executive reward that gets made up if it comes in under the upgrade fee, or what the star in the corner of a sign usually means. The book is full of things like that, plus the buy and skip calls for every aisle.
Yes. Every page is about the Costco warehouses in the US. Prices have "about" in front of them because they move and every warehouse runs a little different. Fees and policies are given as they stand at the time of writing, with a note to check at your own desk.
Chapter 3 gives you a five-item test to find out for your own house, and Chapter 8 is written for one or two people: what freezes, what keeps, what to split with a neighbor, the twelve things that cost a small household more, and a two-week plan built on one big run.
No. I shop with a list on the back of an envelope and a calculator with real buttons. Where the app helps, like the digital card or looking up an old receipt, the book walks you through it in plain steps.
Yes. It's set in large type on purpose, and because it's on your screen you can make it bigger still by spreading two fingers on the page. It also prints well on plain paper.
No. It's an instant download, 182 pages. It opens on your phone, tablet or computer. Print it at home or at your library if you like paper.
No. I worked there for twenty-six years, but Costco didn't ask me to write this, doesn't pay me and has never seen a page of it.
