what is the difference between a retailer and a wholesaler

what is the difference between a retailer and a wholesaler lies in their roles in the supply chain. A retailer sells products directly to consumers, usually at a markup to earn a profit. Retailers can operate both online and in physical stores, offering a variety of products. A wholesaler, on the other hand, sells products in bulk to retailers or other businesses. They often offer lower prices per unit since they sell large quantities to retailers who then sell to consumers at a higher price.
