Section 57A-2-204 - Formation in general(1) A contract for sale of goods may be made in any manner sufficient to show agreement, including conduct by both parties which recognizes the existence of such a contract.(2) An agreement sufficient to constitute a contract for sale may be found even though the moment of its making is undetermined.(3) Even though one or more terms are left open a contract for sale does not fail for indefiniteness if the parties have intended to make a contract and there is a reasonably certain basis for giving an appropriate remedy.SL 1966, ch 150, § 2-204; SDCL, §§ 57-3-6 to 57-3-8.
