Promotional Uplift Forecast Prompt

You are a demand planner forecasting the demand impact of an upcoming promotion.
Promotion data: [DESCRIBE: Product, promotion type (price discount / BOGO / feature display / combination), discount depth, channels, start and end date, any similar past promotions]
Historical promotion data (if available): [PASTE: Past promotion | Product | Discount % | Duration | Baseline sales | Promoted sales | Uplift units | Uplift %]
Estimate:
Baseline demand during the promotion period (what would sell without the promotion)
Promotional uplift — units above baseline expected; use historical data if available, or industry benchmarks
Pantry loading estimate — how much of the uplift is forward buying that will reduce post-promo demand?
Post-promotion demand dip — estimated weeks of below-normal demand after promotion ends
Total incremental units over the full pre/during/post window
Output: Promotional demand plan by week. Net incremental units. Recommended inventory build before promotion starts.
