How do I educate customers about automatic discounts?

As an e-commerce store owner, I'm struggling to help my customers understand how our automatic discount system works. Many customers seem confused about when and how discounts are applied, leading to customer service inquiries and potential frustration. I want to create clear communication strategies that explain our discount mechanisms transparently, build trust, and help customers feel confident about the value they're receiving without overwhelming them with technical details. How can I effectively educate customers about our automatic discount process?
