Okla. Stat. tit. 12A, § 12A-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.
