Twenty-six years inside American supermarkets — produce, meat, then the manager's office — written down as plainly as one trade can be explained to the people it's practised on. The markdown clock. The floor plan. The five lines on every tag.

"That tag has five separate pieces of information on it. Four of them are useful. The big number is the least useful of the lot."
Chapter 1 · The Price Tag Is A DocumentI am not going to tell you to clip coupons on a Sunday or to eat beans for a month. I am going to tell you how the building works.
I started at seventeen, pushing carts in a parking lot in the rain, and I finished as the manager of a mid-size store with a hundred and forty people on the schedule. In between I ran produce for four years and meat for six.
Which means I have personally set more prices, printed more markdown stickers, and thrown out more good food than I care to write down.
Nothing in this book is a secret in the sense of being hidden. Every single thing in here is done in the open, in front of the customer, every day of the week. It is simply that almost nobody has ever been told what they are looking at.
The strip of white plastic along the front edge of the shelf. The rack at the end of the dairy run. The reason the first thirty feet of the store look the way they do. The last two digits of the price, which are not decoration — they are a code the staff read at a glance, and it costs the store nothing to keep printing it where you can see it too.
Every chapter opens with the situation as you actually meet it in the store. Then it explains what is happening behind that situation, and why. Then it tells you exactly what to do about it, in an order you can follow on your next trip.
Where a method does not work, or only works at certain stores, or has a catch, I say so inside the chapter rather than burying it at the end. That is the whole arrangement.
One of these approaches asks you to spend more time, more effort and more discipline every single week. The other asks you to understand the building once.
Plus a start-here road map for your very next trip, 30 illustrations drawn from the floor, and two appendix sheets you can copy and carry.

"I read the chapter on the last two digits on a Tuesday night and went in Wednesday morning. Everything on that endcap I'd been buying for two years was the regular price with a sign over it. Two years."
Marlene R. · Ohio"Fifty-one years old and nobody ever told me the little number in the corner of the tag was the one that mattered. My husband thinks I've started doing maths in the aisle. I have."
Dee W. · North Carolina"The bit about where each department puts its reduced rack. I found four of them in my own store on one trip. I'd walked past three of them every week since it opened."

I'm Jimmy. I spent twenty-six years in American supermarkets and I retired in 2024.
I started at seventeen, pushing carts in a parking lot in the rain, which is where you learn the trade from the ground up whether you want to or not. I ran produce for four years. I ran meat for six. I finished as the manager of a mid-size store with a hundred and forty people on the schedule.
I set the prices. I printed the markdown stickers. I built the planograms and walked the floor at five in the morning while the scan was running. And I threw out an amount of perfectly good food that I still think about.
None of it was a conspiracy. That's the part people get wrong. A supermarket is not out to rob you — it is a machine built to move fifteen to fifty thousand different items through a building at a profit, and it is very good at what it does. Everything it does to you it does in plain sight, according to rules, and the rules are learnable.
I wrote this down because my mother-in-law asked me, one afternoon, why the chicken was cheaper at eight in the morning. I started explaining and I did not stop for four hundred pages of notes. This manual is what those notes became.
The floor plan was drawn by somebody who was paid well to draw it that way. You are allowed to know how it works.

It is ordinary retail practice, described by somebody who spent twenty-six years doing it. None of it is hidden — every bit of it happens in the open, in front of the customer, every day of the week. What it isn't is explained to anybody.
I'll also say plainly what the book says: prices, store policies, promotional calendars and price-ending conventions differ by chain, by region and by year. Every figure in these pages illustrates an arithmetic problem, not a promise of a result. Check everything against your own store — that's what the price book page is for.
The videos are one idea at a time, in whatever order I think of them. This is the whole trade in order — twenty-five chapters that lean on each other, built so that chapter four sets out the unit price and half the book after it assumes you've read it.
You can't build that in eight-minute pieces. And you can't take a video into the aisle with you.
Because of who I wrote it for. This is a manual about not overpaying for things — putting it behind a price that makes you wince would be a poor advertisement for the contents.
$27 is the launch price, down from $47. It's roughly one ordinary shop, and rather less than the food most people throw away in a month.
A PDF — the complete 138-page illustrated First Edition — delivered the moment you order. It opens on a phone, a tablet or a computer, and it prints at home if you'd rather hold it. There's nothing to install and nothing to subscribe to.
The tag chapters, the unit price, the markdown window and the service desk chapters work anywhere there are printed shelf tags and a department that reduces food. The layout chapters describe the big-format store specifically — and the second appendix sheet exists precisely because one store cannot be good at everything.
Wait — one thing
Twenty-six years behind the counter, twenty-five chapters, and the three things to do on your very next trip. The launch price is $27, down from $47.
