Marketing wants a flash sale: [THE DISCOUNT, THE PRODUCTS, OUR MARGIN ON EACH, EXPECTED LIFT, INVENTORY DEPTH, WHAT FULL-PRICE SALES WE WILL CANNIBALIZE]. Sanity-check it: the unit math (does the lift cover the discount at our real margins), the cannibalization estimate from the last promotion, the customers we are training to wait for sales, the support and fulfillment load spike, and the guardrails that make it a tool instead of a habit - duration cap, category cap, frequency cap.
