Discount from the amount of the order(cumulative) 1.5-2.3
UPDATE 29.07.2016: add guests to customer groups for oc 2.x UPDATE 20.11.2016
I rule out an issue with the status of the completed order. Now the completed order is taken from the store settings. previously considered complete order status ranym 5 (Completed / transaction is completed)
modified structure under 2.3.x
Now only applies a maximum discount. before all discounts applied by the user who falls.
He added field to exclude products from the discounts. the exception applies only to the amount of discounts on reservation
