I was looking for a plugin like this for several years. I have now been using it for over 6 months and love it. It has allowed me to discount an add-on without discounting the product. Support has been fantastic. I use several other Barn2 plugins and they all work great.
Excellent discount management plugin that has allowed us to easily add quantity break discounts to our website. Simple to set up, great instructions and comprehensive discounting options. Most importantly, it integrates perfectly with other Barn2 plugins, such as Woocommerce Product Options which, from experience, cannot be said for plugins from other developers.
