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