Discounts: Offer a % cart discount with max cap fixed value
This is a common promotion: Offer customers a 20% discount on small orders but cap this at e.g. $50.
So orders up to $250 would receive a full 20% discount, and orders greater than that would not receive more than a $50 fixed discount.
This can be done with code but it's very tedious. Some native support would be wonderful!
