Use separate single-threshold discount codes for each tier

Create one Advanced Discount Code campaign per tier (each campaign uses a single Order Discount module with one percentage and one minimum purchase amount). For example: create code BF10 -> 10% off with minimum €100; code BF15 -> 15% off with minimum €150; and code CM20 -> 20% off with minimum €200. Communicate the appropriate code to each customer segment from your CRM. Multiple campaigns/codes can be active at the same time. Note: the app cannot enforce customer recency or other customer-targeting rules — you must handle segmentation and only share the relevant codes with targeted customers.
