C.R.S. § 4-2-326

(1) Unless otherwise agreed, if delivered goods may be returned by the buyer even though they conform to the contract, the transaction is: (a) A “sale on approval” if the goods are delivered primarily for use; and (b) A “sale or return” if the goods are delivered primarily for resale. (2) Goods held on approval are not subject to the claims of the buyer’s creditors until acceptance; goods held on sale or return are subject to such claims while in the buyer’s possession. (3) Any “or return” term of a contract for sale is to be treated as a separate contract for sale within the statute of frauds section of this article (section 4-2-201 ) and as contradicting the sale aspect of the contract within the provisions of this article on parol or extrinsic evidence (section 4-2-202 ). (4) The provisions of this section shall not apply to the placement of works of fine art on consignment, which shall be governed by the provisions of part 1 of article 15 of title 6 .
