Formetal Engineering submitted to Presto a sample and specifications for precut polyurethane pads to be used in making air-conditioning units. Formetal paid for the goods as soon as they were delivered but subsequently discovered that the pads did not conform to the sample and specifications in that there were incomplete cuts, color variances, and faulty adherence to the pads paper backing. Formetal then informed Presto of the defects and notified Presto that it would reject the pads and return them to Presto, but they were not returned for 125 days. Presto argued that it was denied the right to cure because the goods were not returned until some 125 days after Formetal promised to do so. Was there a breach of the contract? Did the buyer (Formetal) do anything wrong in seeking its remedies?
