The term 'MIDDLEMAN's Transaction' refers to a resale, which is the act of selling goods or services that were originally purchased from another seller. This type of transaction is often used by businesses to purchase goods in bulk at a discounted rate and then resell them at a higher price. It is also used by individuals who buy items from one source and then resell them to another. This type of transaction is beneficial for both buyers and sellers as it allows them to get a better deal on the goods or services they are purchasing.
