Use it for incremental discounts, based on units purchased. Buy 6 units get 150$ off, buy 9 get 250$ off. Only app that solved this. Support is first class. Recommend.

Very nice and clean app! The support team is very helpful and they respond very fast. I had some issues with making the app work with the theme I'm using, they are on it and I think everything is good now or in about 5 minutes from now. Recommended.
