The SCC Bookstore contracts with GraduationCentral to buy 500 blue caps and gowns. The contract states that delivery is to be made at the Sylva campus bookstore "on or before April 15, in anticipation of a May 15 graduation ceremony." The shipping container holding the caps and gowns to fill the order is washed overboard in a storm and sinks in the Pacific on April 1. GraduationCentral emails the bookstore that they have caps and gowns to fill the order but the order will now arrive on April 20 but receives no reply. The SCC bookstore orders replacement caps and gowns from GownsRUs with scheduled delivery for April 20. On the morning of April 20, two trucks arrive at the SCC bookstore. The bookstore accepts the shipment from GownsRUs but refuses the shipment from GraduationCentral. Did the SCC Bookstore breach the contract with GraduationCentral?
