Whereas under common law the disparity between the fineprint terms in the parties’ forms would have prevented the consummation of a contract when these forms are exchanged, Section 2-207 recognizes that in many, but not all, cases the parties do not impart such significance to the terms on the printed forms…. Subsection 2-207(1) therefore provides that “[a] definite and seasonable expression of acceptance or a written confirmation . . . operates as an acceptance even though it states terms additional to or different from those offered or agreed upon, unless acceptance is expressly made conditional on assent to the additional or different terms.” Thus, under Subsection (1), a contract is recognized notwithstanding the fact that an acceptance or confirmation contains terms additional to or different from those of the offer or prior agreement, provided that the offeree’s intent to accept the offer is definitely expressed, see Sections 2-204 and 2-206, and provided that the offeree’s acceptance is not expressly conditioned on the offeror’s assent to the additional or different terms. When a contract is recognized under Subsection (1), the additional terms are treated as “proposals for addition to the contract” under Subsection (2), which contains special provisions under which such additional terms are deemed to have been accepted when the transaction is between merchants. Conversely, when no contract is recognized under Subsection 2-207(1)-either because no definite expression of acceptance exists or, more specifically, because the offeree’s acceptance is expressly conditioned on the offeror’s assent to the additional or different terms-the entire transaction aborts at this point.
