Secure Courier, Inc., has a requirements contract with Petro Distribution Corporation that obligates Petro to supply Secure with all the gasoline it needs for its delivery vehicles for one year at $2.30 per gallon. A clause inserted in small print in the contract by Secure, and not noticed by Petro, states, "The buyer reserves the right to reject any shipment for any reason without liability." For six months, Secure orders and Petro delivers under the contract without any controversy. Then, because of a war in the Middle East, the price of gasoline to Petro increases substantially. Petro tells Secure it cannot possibly fulfill their contract unless Secure agrees to pay $2.50 per gallon. Secure, in need of the gasoline, agrees in writing to modify the contract. Later that month, Secure learns it can buy gasoline at $2.40 per gallon from Refined Oil Company. Secure refuses delivery of its most recent order from Petro, claiming, first that the contract allows it to do so without liability, and second, that it is required to pay only $2.30 per gallon if it accepts the delivery. Discuss Secure's contentions.
