Pricing is at the sole discretion of the retailer. Outputs are planning estimates only. Tax treatment and retailer margin may vary by market, buy price, promotional mechanics and accounting treatment.

Commercial interpretation

Use the verdict to decide whether to repeat, renegotiate or redesign the event. A strong promo should be profitable after realistic cannibalisation and funding; a weak promo needs a strategic reason, a better mechanic or a lower investment ask.
