Okla. Stat. tit. 12A, § 2-507
Oklahoma Code Comment
(1) Previous Oklahoma law is in accord. Emerson-Brantingham Implement Co. v. Ware, 71 Okl. 19, 174 P. 1066 (1918); Haynes v. Brown, 18 Okl. 389, 89 P. 1124 (1907); Lodwick Lumber Co. v. E. A. Butt Lumber Co., 35 Okl. 797, 131 P. 917 (1913).
(2) This section has a twofold purpose. First, it provides that the buyer's tender of the purchase price is a condition to his rights to the goods, unless otherwise agreed. See also Section 2-511. Previous Oklahoma law is in accord. Weaver v. Bashore, 97 Okl. 237, 223 P. 142 (1924). Second, if payment was demanded on delivery, his rights to retain or dispose of the goods is conditional upon his making the payment. Therefore. if a check is given in payment at the time of delivery, but is thereafter dishonored, he has no rights to retain or dispose of the goods as against the seller. Sec. 2-403, however, provides that the purchaser has the power to convey good title to a bona fide purchaser for value. Also, if the goods were fraudulently obtained without payment, this section would apply. See also Section 2-701 on buyer's insolvency.
