Which of the following is an advantage of e-commerce?

E-commerce often boasts lower operational costs compared to traditional brick-and-mortar stores. This is because online businesses can avoid expenses like physical storefront rent, extensive utility bills, and a large sales staff. They can operate from warehouses or even home offices, significantly reducing overhead. While there are costs associated with website maintenance, marketing, and shipping, these are often less than the combined expenses of a physical retail space. A "more relaxed checkout procedure" is subjective and not a guaranteed advantage; some online checkouts can be complex. "Minimal interaction required with the customer" is generally a disadvantage for building customer loyalty and addressing issues, not an advantage.
