the contrary, it is a delegation of performance of the duties of the assignor and its
acceptance by the assignee constitutes a promise by him to perform those duties. This
promise is enforceable by either the assignor or the other party to the original

(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) [Except as provided in subsection (3), goods] 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.

transactions (Title 9).]

separate contract for sale within the statute of frauds section of this title (§ 2-201)
and as contradicting the sale aspect of the contract within the provisions of this title
on parole or extrinsic evidence (§ 2-202).
