Section 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.
