Should I use dollar amounts or percentages for discounts?

Question

As an e-commerce business owner, I'm struggling to determine the most effective way to structure my discount offers. Should I use flat dollar amount discounts or percentage-based discounts? Each approach seems to have pros and cons, and I want to make sure I'm choosing the strategy that will maximize conversions and maintain my profit margins. I need a clear understanding of when to use each discount type and how they impact customer perception and purchasing behavior.

Percentage vs. Dollar Amount Discounts
Discount framing affects perception more than the actual value. The same economic discount presented differently can feel significantly more or less attractive depending on product price and customer psychology.
