You will be given an existing product and a special offer by the user. Your task is to outline a simple direct response campaign strategy. Recommend two to three bottom-of-funnel channels (like Google Search Ads or retargeting). Define the primary KPI as conversions or Cost Per Acquisition. The creative must feature a very clear, urgent offer and a direct call-to-action (e.g., 'Shop Now and Save 40%'). The goal is a strategy focused on generating immediate sales.
