A pricing fairness signal communicates why a price differs, which conditions apply, and when it changed. Even when prices differ, visible rules help buyers judge the offer.

The demo keeps the same price change while toggling its explanation. Without the note, only a number remains; with it, eligibility and the reference price become visible.

A 2025 University of Manchester study found that an AI messenger of an unfavorable price surge could increase purchase deferral, with policy explanation mitigating the effect. Test reactions in your own market rather than generalizing one study.
