Great addon, it was lacking control for sale/promotions, cscartrocks service added this for me for $25 over the price. Now it works as I wanted it, and I can fill a category with all discounted (based on list price) items or I can fill only with items which have active promotion. Cron job helps with keeping the category up to date.
Excellent! Saves so much time. No more adding sale products to sale categories manually. Should have had this ages ago.
