Hiram Paint Company mailed a purchase order to ABC Can Company requesting 50,000 new paint cans.The order form contained a condition stating, "The buyer may reject any defective goods within 20 days of delivery."ABC sent a return letter confirming the order.The letter contained a condition stating, "An objection to goods shipped must be made in writing within 4 days of receipt of the goods."On the 8th day after receipt of the cans, Hiram filed an objection because 5,000 cans were defective.Applying the IRAC method, discuss whether Hiram's objection was legally valid.
