Okla. Stat. tit. 12A, § 12A-2-504: Shipment by Seller

Where the seller is required or authorized to send the goods to

the buyer and the contract does not require him to deliver them at a

particular destination, then unless otherwise agreed he must

(a) put the goods in the possession of such a carrier and

make such a contract for their transportation as may be reasonable

having regard to the nature of the goods and other circumstances of

the case; and

(b) obtain and promptly deliver or tender in due form any

document necessary to enable the buyer to obtain possession of the

goods or otherwise required by the agreement or by usage of trade;

and

(c) promptly notify the buyer of the shipment. Failure to

notify the buyer under paragraph (c) or to make a proper contract

under paragraph (a) is a ground for rejection only if material delay

or loss ensues.
