# Profit Cannibalization in Discounting

Profit cannibalization is what [[entity-rafi-mohammed|Rafi Mohammed]] calls the *"scourge of discounting."* It occurs when a discount designed to attract new, price-sensitive customers is instead taken by *existing* customers who would otherwise have paid full price.

Why it is so costly: profit is derived from the **final dollars** of a price (see [[quote-profit-from-final-dollars]]). A discount handed to a willing full-price buyer is therefore a direct, **dollar-for-dollar deduction from net profit** — not a marketing cost cushioned by margin.

The entire objective of sophisticated discounting is to **limit** this cannibalization while still capturing the incremental revenue that budget-minded buyers represent. The primary control mechanism is the [[concept-discounting-hurdles|discounting hurdle]], which forces price-sensitive buyers to self-identify so full-price buyers keep paying full price. Uncontrolled, cannibalization turns a growth tactic into a margin-destroying error — see [[claim-haphazard-discounting-margin-destruction]]. The unresolved design problem of how much friction to impose is captured in [[question-optimal-hurdle-friction]].
