Represents the type of pricing associated to the selling plan (for example, a $10 or 20% discount that is set
for a limited period or that is fixed for the duration of the subscription). Selling plan pricing policies and
associated records (selling plan groups, selling plans, billing policy, and delivery policy) are deleted 48
hours after a merchant uninstalls their subscriptions app. We recommend backing up these records if you need
to restore them later.
