Hi Jens Jakob

No, that is not possible.

The exlude is meant for the scenario, "If you buy a product from brand a, except product y, you get the discount".

So the only option right now is to add additional logic - either in some code that will remove the discount again, or in the cart where you will disallow the voucher if the cart contains the 'wrong' brands - you can do that using some javascript that will remove the voucher code and re-submit the order.

We have just completed development of a DiscountExtender feature - that is a new extensibility point for the Discounts & Offers.

Then you can create code like this:

public class DiscountFilterCheapProducts : DiscountExtenderBase
    {

//Additional product discount logic

        [AddInParameter("Cheap price"), AddInParameterEditor(typeof(IntegerNumberParameterEditor), "minValue=0;maxValue=1000;allowNegativeValues=false;localizeValues=true;")]
        public int CheapPrice { get; set; }

        public DiscountFilterCheapProducts()
        {
            CheapPrice = 100;
        }

        public override bool DiscountValidForProduct(Product product)
        {
            return product.Price.Price <= CheapPrice;
        }

//Additional order discount logic

        [AddInParameter("Favorite name"), AddInParameterEditor(typeof(TextParameterEditor), "")]
        public string FavoriteName { get; set; }

        public DiscountFilterForMarta()
        {
            FavoriteName = "Marta";
        }

        public override bool DiscountValidForOrder(Order order)
        {
            var valid = false;

            if (!string.IsNullOrEmpty(FavoriteName) && !string.IsNullOrEmpty(order.CustomerName))
            {
                valid = order.CustomerName.StartsWith(FavoriteName, System.StringComparison.OrdinalIgnoreCase);
            }
           
            return valid;
        }

    }

But that is not ready for release yet...
