by which to reduce the recurring fee; also increments months used on the
discount and generates an invoice detail describing it.
+If the configuration option 'discount-show_available' is enabled, and this
+package is eligible for a prepayment discount but doesn't have one, an
+invoice detail will be generated to describe the available discounts.
