How can I track if discounts are cannibalizing full-price sales?

As an e-commerce manager, I'm struggling to understand whether my current discount strategies are genuinely driving additional revenue or simply reducing profit margins by encouraging customers who would have purchased at full price to wait for sales. I need a systematic approach to analyze the impact of discounts on our overall sales performance, customer behavior, and long-term revenue generation. How can I confidently measure whether my promotions are creating value or undermining our pricing strategy?
