I have a discount that gives 20% of 1 item in the basket. The most
expensive item is given the discount. This works fine. I now want to
exclude watches and sungl***** from this. I tried using an expression
where Product.Category does not include these two categories. But
because an item in the basket is not a sunglass or watch the discount
is applied but its selecting the more expensive item which is the
sunglass or watch. How can I exclude these products from getting this
discount applied to them.
