It's very frustrating that we can't set a maximum for discounts (only minimum). There are apps for that but it doesn't seem fair to have to pay for an app to do such a basic thing.
Whenever I create any kind of discount, everyone takes advantage of it by ordering 10 items, and then, of course, the discount is applied to the entire cart!
I just want to sometimes create a discount for ONE item, so they can try it out. This way, even if they add 10 items to the cart of the same product, only one of them will get the discount.
