Question: Bell, purchasing agent for the Hiram Paint Company, mailed a purchase order to the ABC Can Company requesting 50,000 new paint cans. The order form contained, among others things, a condition stating, "The buyer may reject any defective goods within twenty days of delivery." The ABC Can Company sent a return letter confirming the order. The letter contained a condition stating, "An objection to goods shipped must be made in writing within five days of receipt of the goods." On the eighth day after receipt of the shipment of cans, Bell filed an objection to 5,000 cans he stated were defective. Is this objection legally valid?
