This is a new feature in 9.7 where you’ll be able to chose a box in your Price Groups Discount window to make all products eligible for that discount unless you exclude it. This feature takes every product that you currently have in your store, plus all the products you add in the future into this price group automatically by default. Then if there is a product you don’t want to be included, you can simply go in and turn it off, or exclude it from the price group.
