Moulton Cavity & Mold, Inc., agreed to manufacture twenty-six innersole molds to be purchased by Lyn-Flex. Moulton delivered the twenty-six molds to Lyn-Flex after Lyn-Flex allegedly approved the sample molds. However, Lyn-Flex rejected the molds, claiming that the molds did not satisfy the specifications exactly, and denied that it had ever approved the sample molds. Moulton then sued, contending that Lyn-Flex wrongfully rejected the molds. Lyn-Flex argued that the Code's perfect tender rule permitted its rejection of the imperfect molds, regardless of Moulton's substantial performance. Decision?
