A Standard Clause allowing a buyer to obtain the best possible price on goods or services from a seller by requiring it to provide the buyer with the lowest price among all buyers in that market. If the seller wants to offer a different buyer a lower price, it must also first offer that price to the buyer with the most favored customer clause (MFC), also known as a most favored nation clause. MFCs can implicate US antitrust laws, which analyze the enforceability of MFCs using a rule of reason analysis. This Standard Clause addresses the price of goods and has integrated drafting notes with important explanations and drafting tips.
