Acceptance of goods occurs when the buyer a. after a reasonable opportunity to inspect the goods signifies to the seller that the goods are conforming or that the buyer will take or retain them in spite of their nonconformity; or b. fails to make an effective rejection ( section 554.2602, subsection 1 ), but such acceptance does not occur until the buyer has had a reasonable opportunity to inspect them; or c. does any act inconsistent with the seller’s ownership; but if such act is wrongful as against the seller it is an acceptance only if ratified by the seller. 2.
