Cohn advertised a 30-foot sailboat for sale in The New York Times. Fisher saw the ad, inspected the sailboard, and offered Cohn $4,650 for the boat. Can accepted the offer. Fisher gave Cohn a check for $2,535 as a deposit on the boat. He wrote on the check, "Deposit on aux sloop, D'arc Wind, full amount $4,650." Fisher later refused to go through with the purchase and stopped payment on the deposit check. Cohn then sued Fisher for breach of contract. He asked for damages of $1,679.50. This represented the $1,650 differences between the contract price and the sale price plus $29.50 in incidental expenses in reselling the boat.
