Whether Different Types of Discounts Can Be Combined
This section explains whether the various discount services we offer can be combined. There are three types of discounts — product discounts, order discounts, and shipping discounts — and there are cases where they can be used together and cases where they cannot.
We'll clearly explain the specific rules and restrictions for combining discounts, providing helpful reference information so you can make the most of your savings.
