Title 11, Chapter 2, Section 304
Price payable in money, goods, realty, or otherwise.
(1) The price can be made payable in money or otherwise. If it is
payable in whole or in part in goods each party is a seller of the
goods which he is to transfer.
(2) Even though all or part of the price is payable in an interest
in realty the transfer of the goods and the seller's obligations
with reference to them are subject to this article, but not the
transfer of the interest in realty or the transferor's obligations
in connection therewith.
