Is my code field logic preventing stacking and confusion?

I'm developing an e-commerce platform and want to ensure my discount code implementation prevents unintended stacking or confusion. Currently, I'm unsure if my existing logic effectively stops customers from combining multiple discounts or accidentally applying conflicting promotional codes. I need a comprehensive strategy to manage discount code interactions, prevent abuse, and maintain a clear, predictable customer experience during checkout. What best practices can help me create robust discount code validation rules?
