So, any e-retailers must need to excite their potential online consumers have e-platforms click in their websites to search products desires or needs in preference more than walk in stores to search products method on street. However, I believe that their online product photos whether are attractive or their wirelesses are high or rapid mobile linking speed will influence their online businesses in success. So, online e-service and wireless rapid speed performances will influence every online retailer individual success or fail, instead of product photos whether are clear or information search whether is rapid or enough and sale price whether is low or reasonable and after sale support performance whether is satisfactory factors.

In management view, it is " division of labours" concept to be used in Amazon customer service department. Also, it has large warehouse, it applied robotics to help warehouses to find and delivery any kinds of products to the correct delivery positions in order to delivery the product to the client's destination in the short time. So, robotics had help Amazon to reduce warehouse staffs' times and raises efficiencies in warehouses. When the warehouse workers can receive the client name and address and product kind and product purchase number data from its Amazon website e-retail store channel. Then, its warehouse staffs can follow these data to let robotics to know where they need to arrive to find the product(s) and deliver them to the right positions and let the lorry drivers to deliver to either airport (overseas buyers) or local destination ( home country buyers).
