A grouped product is a cluster of simple products clubbed together to form a single entity. The grouped product won’t have a price or other features. The identity of the grouped product is created by a number of child products that have unique features of their own. As soon as you create a grouped product, you can add at least one child product to the grouped product. Your customers can purchase any of the child products from the grouped product individually as well. eg: A set of six glasses.
