Discount not in Combination with sale items

I am facing an issue about discounts. A client of mine has 10% discount for first time e-mail subscribers. But also a lot of sale items (with compare at price), she doesn’t want that customers buy sale items with the e-mail subscription discount code.

So next to all collections, I made a SALE collection. In the discount settings I selected all collections except for the SALE collection. Most products are next to the SALE collection also in another collection.

How can I automaticly exclude products to be checked out with this discount code?

You could set up a collection with all products not on sale and only allow it to work with products in that collection. :wink:
