Final answer:
A store's inventory is kept on the sales floor and in warehouses; Amazon exemplifies the use of large warehouses for efficient inventory management and distribution.
Step-by-step explanation:
Other than in the stockroom, a store's inventory is primarily kept on the sales floor, arranged within various departments. In traditional retail settings, inventory is displayed on shelves or in display cases that are accessible to customers. However, innovative companies like Amazon, which started solely as an online retailer, hold their inventory in large, low-rent warehouses strategically placed around the world. These warehouses are equipped with advanced technology and automation which helps in maintaining low average costs per sale. This setup allows businesses to take advantage of economies of scale. Although initially lacking a physical retail presence, Amazon has now expanded into brick-and-mortar stores in selected areas, offering a traditional shopping experience, in addition to their vast online marketplace and highly efficient warehousing system.Conclusion In summary, inventory is stored in locations that both support sales efforts and efficiency in distribution, whether on store shelves or in large centralized warehouses, with the latter being a hallmark of online retail giants like Amazon that leverage economies of scale for competitive advantage.
