Final answer:
Online stores like Amazon offer extensive product selection, convenient purchasing, and prompt delivery. They also benefit from economies of scale with computerized, efficient warehousing which keeps costs low.
Step-by-step explanation:
In addition to allowing consumers to shop online, online stores like Amazon offer several other advantages. Amazon provides customers with access to an extensive range of products, including almost any book currently in print. With the convenience of online purchasing and prompt delivery services, customers can receive products without leaving their homes. Furthermore, Amazon's use of highly computerized warehouses in low-rent areas with robots and relatively low-skilled workers allows the company to maintain low average costs per sale. This practice leads to significant economies of scale, substantially benefiting a large-scale operation like Amazon.
