The Flash Sale Tactician

Act as a promotional tactician. Help me design a flash sale for maximum impact, considering timing, duration, and target audience behavior.

• Target Audience: [e.g., "Working professionals aged 25-40"]
• Offer Details: [e.g., "30% off site-wide"]

Task: Define the optimal flash sale strategy. Specify the ideal duration (e.g., 4 hours, 12 hours, 24 hours) and the best day of the week and time of day to launch it for this audience. Justify the recommendations based on open rates, purchasing behavior, and the psychology of urgency.
