A more thorough explanation:

A retailer is a person or business that sells goods directly to the public or consumers. They sell products for personal use, rather than for resale.

Examples of retailers include:

• A clothing store that sells clothes to individual customers
• A grocery store that sells food and household items to consumers
• An electronics store that sells gadgets and devices to individual customers

These examples illustrate the definition of a retailer because they all sell products directly to consumers for personal use. They are not selling to other businesses or individuals who plan to resell the items.
