"And trade knowledge stays inside the trade, because nobody on the inside has any reason to hand it out. I'm on the outside now. So here it is."

Six numbers on that label. Most people read one.
That's the card price. Or the app price, or the price after a digital coupon somebody has to load first. It's the number the tag is built to sell you. Read the tag for the condition before you read it for the number.

Before you buy
Decode the tag above and decide for yourself — that's why it's here with no email form in front of it. What the book adds is the view from behind the swinging doors: why the markdown happens when it happens, and what the store owes you when the tag and the register disagree.
Then it's the right book — the method runs on paper and a pen. There's a chapter on digital-only prices with the exact sentence to say at the desk to get the week's offers loaded for you, without an app.
Prices move; the book says so on page one. Structure doesn't. A dairy rack will hand you the oldest jug in 2030 the same as today — and every future revision is free.
Fourteen days, full refund, no questions. Email and the $39 goes back. You keep the four forms either way.
I spent thirty-eight years watching people apologize for asking. You do not owe anybody an apology for reading a shelf tag.
