The idea in one line. A price list is not a set of prices. It is a ladder the customer climbs with her eyes in the first ten seconds — and a margin structure the business climbs every month.
Three rungs. ENTRY (opening price point): the lowest credible price in the category. It recruits, it creates the "this brand is for me" feeling — and it must be a real product, not a decoy. CORE: the middle, where most units and most margin live; the price the customer expects to pay here. HERO: the top — it anchors perception, makes the core look reasonable and carries the story; it sells thin and matters much.
Why it matters. Without architecture, prices drift with costs and the range reads as random: two similar coats at 190 and 240 with no visible reason destroy trust faster than any single high price. With architecture, the customer understands the range without a sales assistant, and margin becomes a design instead of an accident.
The margin side. Each rung carries its own target markup and its own markdown risk: entry rarely marks down, hero is planned as image and judged by what it does for the rest of the range. The "good-better-best" logic is old; the discipline is modern — the gap between rungs must be explainable by something the customer can see or touch (fabric, construction, brand story), never by your cost alone.
The trap. Too many rungs. Five price points in one category mean the customer cannot see the logic and the merchandiser cannot see the margin. Three rungs, clearly spaced, beat seven.
The bridge. A price ladder is a hypothesis about willingness to pay — and it is measurable. Full-price sell-through by rung tells you whether the customer agreed with your architecture: if entry sells through and core does not, the ladder is too steep; if hero outsells its plan, the brand is underpriced.
Practice. Take one category from any brand's site. List the price points, group them into entry / core / hero, and name the visible reason for each step. If you cannot name it, the customer cannot either.
