If the discount rule on cart is used, the system generates a coupon for the same amount of the discount to apply.
Assumed we have created a rule that applies a 20% discount for amounts higher than 200£ on cart, we will have a situation like this.
To change the coupon name that will be generated, go to the tab Settings in plugin options panel and add your text in the field Coupon Label.
Information about the coupon used will be available also in order detail page.
