On November 20th, 2017 we released an update for additional coupon options.
Please note, this change requires the 2015 Cart, Responsive Design, & the Class Design Update users.
Here are the additional options we added:
1. The 'Percent Off' tab now allows for a minimum purchase amount as well as a maximum discount amount.
2. Specific date ranges can now be added.
3. Coupon Eligibility can now be set by specific product, department, or category. This only applies to items that are marked as 'Percent Off'
