Final answer:
The company that initially sold exclusively through its webshop and later opened physical stores is using a multichannel retail system, which is a hybrid retail system.
Step-by-step explanation:
The company initially only had sales through its webshop and later expanded by opening several physical stores. This indicates that the company is not exclusively an online retailer, nor does it only operate through brick-and-mortar outlets.
Therefore, the system currently being used by the company is a Hybrid retail system, specifically a multichannel retail system. A multichannel retail system combines different methods of shopping available to consumers, such as online and in-store. For instance, companies like Amazon and L.L. Bean also began with online sales and later integrated physical retail stores, thereby leveraging economies of scale and expanding their market presence.
