## Frequently Asked Questions

**How does the discount calculation order work?**
Discounts are applied in a strict sequence: first the store coupon, then the platform cross-store threshold, followed by the VIP discount, and finally the red packet deduction.

**Can I use this to plan my 11.11 shopping cart?**
Yes, you can use `get_threshold_analysis` to see exactly how much more you need to add to your cart to trigger the next platform-wide discount tier.

**What is the difference between a store coupon and a platform threshold?**
A store coupon is specific to a single merchant, while the platform threshold is a cross-store discount applied by the platform for every fixed increment spent.
