It is currently not possible for customers to see how much they have saved. No one likes having a physical savings card, it's better that they can see for themselves where they are with savings at the moment. (Think of this as an extra cool feature for the app, for example.) What I also miss about the savings system is that you can't choose how many products to discount, for example. For me, he automatically gives 10% on all products, while they get 10% on 1.
