Cummings ordered two model X Super Fidelity speakers from Jamestown Wholesale Electronics, Inc. Jamestown shipped the speakers via United Parcel Service, C.O.D. (collect on delivery), although Cummings had not requested or agreed to a C.O.D. shipment of the goods. When the speakers were delivered, Cummings refused to accept them because he would not be able to inspect them before payment. Jamestown claimed that it had shipped conforming goods and that Cummings had breached their contract. Had Cummings breached the contract? Explain.
