Casein, a protein derived from milk, is used to make cheese and to process many other foods. Erie Casein Co. contracted with Anric Corp. to supply one thousand pounds of casein for about $1 per pound. Half was to be delivered in March. By May of the first year, Anric had not finished its first delivery because it was having difficulty obtaining the casein . Erie waited until August, but it finally obtained its casein elsewhere at a price of $1.45 per pound. Erie sued Anric for the extra money it had paid. Anric argued that Erie had no right to the difference because the price of casein was sky-high and thus it was not Anric's fault. Who wins and why?
