A grouped product consists of simple standalone products that are presented as a group. You can offer variations of a single product or group them by season or theme. Presenting a grouped product can create an incentive for customers to purchase additional items. A grouped product provides an easy way to offer variations of a product and list them all on the same page.
For example, you might sell open stock flatware and list every type of utensil that is used in a formal place setting. Some might order multiple salad forks, fish forks, dinner forks, dinner knives, fish knives, butter knives, soup spoons, and dessert spoons. Other customers might order a simple fork, knife, and spoon. Customers can order as many of each item as they want.
Although they are presented as a group, each product in the group is purchased as a separate item. In the shopping cart, each item and the quantity purchased appears a separate line item.
