Title 11, Chapter 2, Section 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.
