Answer:
D. Higher costs due to customer support is not a benefit to smaller retailers of online shopping.
Step-by-step explanation:
Smaller retailers often incline themselves doing affordable business and save on cost as much as they can. Unlike large retailers, small retailers cannot afford to run a dedicated customer support service separately for their business online.
But looking at the trend of modern-day e-commerce, it becomes mandatory for them to dispense customer support service which doesn't prove to be very beneficial to the business.
