Don't Discount What Will Sell Out. Discount What Won't Move.

Don't Discount What Will Sell Out. Discount What Won't Move.

A blanket 20% off discounts two opposite products at the same rate: the hero that would sell out at full price this week, and the long-tail SKU that hasn't moved in ninety days. One discount was pure transfer. The other was probably too shallow to matter. Both were priced by the same button.

Discounts should follow inventory reality, not ignore it. Velocity pays full price; stagnation earns attention; dying stock needs clearance math, not promo math.

Three inventory states, three pricing postures

Velocity (selling fast, low cover). Discounting here is paying for speed you already have — and risking a stockout that kills full-price demand and trains "out of stock" disappointment. Exclude low-cover heroes from sitewide depth, or cap their depth hardest. Scarcity needs no subsidy.

Healthy (steady sell-through, good cover). Hold price. This is where behavior-gating earns most: full price for the ready, minimal nudges only for demonstrated hesitation. Blanket depth on healthy stock converts the already-convinced at scale — the largest transfer surface in the store.

Stagnant (low velocity, high cover, aging). This is where price belongs — plus bundles, threshold gifts, and placement, because deep percentages alone rarely clear truly dead stock without destroying the price anchor for everything else. Price stagnant SKUs deliberately while protecting the rest; a targeted 30% on the tail beats a blanket 15% on everything, on margin and on signal.

The sequencing mistake that burns both

Running flash depth on items headed for clearance torches both events: the flash pulls forward the few full-price buyers the SKU had left, then clearance must go deeper to clear a smaller, more price-trained remainder. Sequence instead — flash the healthy (gated), clear the dying (openly), and never let the first borrow the second's assortment.

Watch substitution too. Discounting one variant cannibalizes its siblings: the promoted color sells while the same product in other colors stalls. Aim depth at the slow variant, not the family.

Operate it weekly, not seasonally

A simple weekly loop: flag SKUs by cover and velocity trend, set promo eligibility accordingly (excluded / gated-only / eligible), and review post-promo sell-through net of cannibalized siblings and returns. The eligibility list is the strategy — everything else is execution.

Measure per-SKU incremental contribution with holdouts at the eligibility boundary: identical-velocity SKUs with gated vs. open depth. The SKUs that sell without depth are your transfer map.

The takeaway

One discount rate for all inventory states guarantees two errors: paying for velocity and starving stagnation.

Exclude what will sell out, gate the healthy, aim depth at the tail — and sequence flash and clearance so the first never eats the second.
