24.03.040 Formation in General

(a) 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.

(b) An agreement sufficient to constitute a contract for sale may be found even though the moment of its making is undetermined.

(c) 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.
