In a few words what is the substantive comment on this post:

A retailer is a business that sells products directly to consumers for personal or household use. They typically operate physical stores or online shops, and sell a wide range of products.A wholesaler is a business that sells products to other businesses, such as retailers. Wholesalers typically sell products in larger quantities and at a lower cost than retailers. They may also provide additional services, such as logistics and inventory management.A distributor is a business that acts as a middleman between manufacturers and retailers or other distributors. They may purchase products from manufacturers and then resell them to retailers or other distributors, or they may distribute products on behalf of manufacturers. They also may provide additional services, such as marketing, advertising and sales. An example of a wholesaler would be eBay since the company sells different categories of products from various brands and ships to all parts of the world and who sells at affordable prices and you can also count on them to deliver high-quality goods.. An example of a distributor would be Walmart who engages in both the retail and wholesale business, selling an assortment of merchandise and services worldwide at stores and online at everyday low prices.
