Adds features to PMPro to better manage grouped discount codes or large numbers of unique discount codes with the same pricing. How it Works Adds the ability to create a single ‘parent’ discount code and bulk generate ‘child’ codes with the same settings. The parent code controls all of the pricing, expiration, allowed levels, etc. Once saved, each of the sub codes will act as if they have the same settings as the main code. This is useful for bulk mailing, newsletters, or participation in a Groupon-type program.
