(810 ILCS 5/2-204)
(from Ch. 26, par. 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.
