Can I test different subscription discount models?

As an e-commerce business owner, I'm looking to experiment with different subscription discount models to find the most effective strategy for attracting and retaining customers. I want to understand the various approaches to subscription discounts, how to structure them, and what impact they might have on customer lifetime value and retention. I'm particularly interested in learning about the different types of models, their pros and cons, and best practices for implementation across various industries and product types.
