Optional payment Items are resources that learners can buy when they buy a course which is configured for online payment. You may wish to set up optional payment items for generic categories of items that are available for multiple courses, such as participant packs or accommodation.
You can configure the cost of optional payment items per module or per session, so each course can have its own pricing. Item labels can also be localized so that they are displayed in the user's preferred language, subject to the availability of language bundles.
To manage optional payment items, go to Manage Center > Learning > Optional Payment Items.
