Rules inside one campaign
For product rules of 5% and 20% on the same scope, first-match uses the first qualifying rule, while maximum-savings chooses the larger offer. “Use multiple discounts” does not mean every offer applies consecutively.
Automatic gift campaigns require the multiple-discount strategy. Gift-only campaigns hide selection controls that do not need manual configuration.
