+=item change_discount %opt
+
+Method checks if the given values represent a change in either setup or
+discount level. If so, the existing discounts are revoked, the new
+discounts are recorded.
+
+Usage:
+
+$error = change_discount(
+ setup => {
+
+ # -1: Indicates a "custom discount"
+ # 0: Indicates to remove any discount
+ # >0: discountnum to apply
+ discountnum => [-1, 0, discountnum],
+
+ # When discountnum is "-1" to indicate custom discount, include
+ # the additional fields:
+ amount => AMOUNT_DISCOUNT
+ percent => PERCENTAGE_DISCOUNT
+ months => -1,
+ },
+
+ recur => {...}
