Strike offers to sell Bailey one thousand shirts for a stated price. The offer declares that shipment will be made by Dependable truck line. Bailey replies, "I accept your offer for one thousand shirts at the price quoted. Delivery to be by Yellow Express truck line." Both Strike and Bailey are merchants. Three weeks later, Strike ships the shirts by Dependable truck line, and Bailey refuses to accept delivery. Strike sues for breach of contract. Bailey claims that there never was a contract because his reply, which included a modification of carriers, did not constitute an acceptance. Bailey further claims that even if there had been a contract, Strike would have been in breach because Strike shipped the shirts by Dependable, contrary to the contract terms. Discuss fully Bailey's claims. (See The Formation of Sales and Lease Contracts.)
