Did the substitution of carriers in the third shipment constitute a breach of the contract by GFI? Explain.
GFI, Inc., a Hong Kong company, makes audio decoder chips, one of the essential components used in the manufacture of MP3 players. Egan Electronics contracts with GFI to buy 10,000 chips on an installment contract, with 2,500 chips to be shipped every three months, F.O.B. Hong Kong, via Air Express. At the time for the first delivery, GFI delivers only 2,400 chips but explains to Egan that although the shipment is less than 5 percent short, the chips are of a higher quality than those specified in the contract and are worth 5 percent more than the contract price. Egan accepts the shipment and pays GFI the contract price. At the time for the second shipment, GFI makes a shipment identical to the first. Egan again accepts and pays for the chips. At the time for the third shipment, GFI ships 2,400 of the same chips, but this time GFI sends them via Hong Kong Air instead of Air Express. While in transit, the chips are destroyed. When it is time for the fourth shipment, GFI again sends 2,400 chips, but this time Egan rejects the chips without explanation.
