Points issuance can be set to specific period of time. However, you cannot register a period that overlaps with an already registered period of time.
If you want to force a currently “Active” setting to “Expire”, change the end date to a time earlier than today and the setting will automatically expire.
Modifications made to points per product will be applied to each individual setting.
The discounted price for purchase amount is ‘(Price ± Extra charge (item)) - Product discount’. You can configure the product discount in [Incentives].
