Non-store retailing involves sales made directly to consumers without using physical stores. It includes direct marketing, direct selling, vending machines, and e-tailing. Non-store retailing appeals to time-constrained consumers and is growing faster than store-based retail. It accounts for over 15% of consumer purchases currently. Common forms of non-store retailing include direct selling, direct marketing, direct response marketing, catalog marketing, telemarketing, and e-commerce. Non-store retailing has advantages of lower costs than physical stores and a global reach, but also risks of credit card fraud and connectivity issues.
