Should timers be different from Black Friday?

As an e-commerce professional, I'm wrestling with designing effective countdown timers for Black Friday compared to our standard promotional strategies. My team wants to understand whether Black Friday requires a fundamentally different approach to urgency creation, or if our existing timer tactics can be seamlessly adapted. We're specifically concerned about maintaining customer trust, preventing offer fatigue, and maximizing conversion rates during this high-stakes shopping period where consumers are bombarded with countless promotions and countdown experiences.
