Pre-set limitations in case of discounted products only available with coupon codes

The Backstage ecosystem has already included the feature to specify a maximum cart value and the maximum number of items that can be purchased from a single product (with the main goal to make ticket fraud more difficult). This tool has now been upgraded by our current development, implemented at the request of Budapest Spas. Our new tool allows the limitation of the number of items that can be added to the cart at once, mainly usable for on-sale products that require a mandatory coupon code (this way determining the maximum number of products that can bought with a single coupon code). This development enables more sophisticated and very efficient coupon code campaigns.
