The retailindustry consists of selling merchandisedirectly to the consumer. Retailing began several thousand years ago with peddlers hawking their wares at the earliest marketplaces. It is extremely competitive, and the failure rate of retail establishments is relatively high. Price is the most important arena of competition, but other factors include convenience of location, selection and display of merchandise, attractiveness of the establishment, quality, and reputation.
