This has led to the creation of synonyms for "mail-order selling" that reflect these changes. Some examples of these synonyms include e-commerce, online shopping, distance selling, and direct response marketing. Each of these terms reflects a different aspect of the broader concept of mail-order selling, which includes everything from online stores to traditional catalog shopping.
