Case - Article 2 U.C.C. § 2-206. Offer and Acceptance in Formation of Contract.
(1) Unless otherwise unambiguously indicated by the language or circumstances (a) an offer to make a contract shall be construed as inviting acceptance in any manner and by any medium reasonable in the circumstances: (b) an order or other offer to buy goods for prompt or current shipment shall be construed as inviting acceptance either by a prompt promise to ship or by the prompt or current shipment of conforming or nonconforming goods, but the shipment of nonconforming goods is not an acceptance if the seller seasonably notifies the buyer that the shipment is offered only as an accommodation to the buyer. (2) If the beginning of a requested performance is a reasonable mode of acceptance, an offeror that is not notified of acceptance within a reasonable time may treat the offer as having lapsed before acceptance. (3) A definite and seasonable expression of acceptance in a record operates as an acceptance even if it contains terms additional to or different from the offer.
