Explanation:
According to my research on the UCC, I can say that based on the information provided within the question the offer is governed by the UCC and will be enforced because it is signed and in writing. The UCC enforces any contract or offer that is officially signed by offering party, especially when dealing with purchases of goods valued $500 or more. Since the contract is still valid for another month when the administrator tried to use the discount then Kiko must honor it.
