Who is responsible for buying and selling goods at a profit to small retailers?

The individual or entity responsible for buying and selling goods at a profit to small retailers is typically known as a wholesaler or distributor. Wholesalers purchase large quantities of products from manufacturers and then sell them in smaller quantities to retailers. This process helps retailers maintain inventory without having to deal with the complexities of dealing directly with manufacturers. Additionally, brokers or agents may also facilitate these transactions, acting as intermediaries between manufacturers and retailers.
