The document discusses different types of wholesalers and intermediaries in the wholesale industry. It outlines merchant wholesalers, manufacturers' sales branches and offices, brokers and agents, and commission merchants. Merchant wholesalers independently take title to the goods they handle and can be full-service or limited-service. Manufacturers' sales branches sell goods directly rather than through independent wholesalers. Brokers and agents facilitate sales but do not take title to goods. Commission merchants buy and sell goods for others on a commission basis.
