Which retail format is known for having a narrow but deep assortment of products?

The category specialist retailer is known for offering a narrow but deep assortment of products. This type of retailer focuses on a specific product category, allowing it to provide a wide variety of items within that category, which satisfies extensive customer needs. For example, a category specialist retailer might be a store that specializes solely in sporting goods or electronics, offering numerous brands and products related to that specific category.

This focus on depth rather than breadth means that customers can find more options and specialized items that they might not see in other retail formats, which often carry a broader range of different types of products but do not specialize as thoroughly within a single category. The result is a strong product assortment that appeals to customers seeking variety and expertise in their particular interest area.
