ProSound and Stage Lighting review for Advanced Collections

This app is a MUST have for any ecom shop. It is so much better than the native Shopify collection management. With this app, it will create collections that exclude products with certain tags. It has can include or exclude so many different options and has ALL the operators that Shopify does not have. The company has been very responsive to support and enhancement requests. This seriously should be the number one Shopify app in the store. EVERYONE needs this!
