تمرين 8

On November 23, Blackburn, a dress manufacturer, mailed to Conroy a written and signed offer to sell one thousand sun dresses at $50 per dress. The offer stated that it would ''remain open for ten days'' and that it could ''not be withdrawn prior to that date.''
Two days later, Blackburn, noting a sudden increase in the price of sundresses, changed his mind. Blackburn therefore sent Conroy a letter revoking the offer. The letter was sent on November 25 and received by Conroy on November 28.
Conroy chose to disregard the letter of November 25; instead, she happily continued to watch the price of sundresses rise. On December 1, Conroy sent a letter accepting the original offer. The letter, however, was not received by Blackburn until December 9, due to a delay in the mail.
Conroy has demanded delivery of the goods according to the terms of the offer of November 23, but Blackburn has refused. Does a contract exist between Conroy and Blackburn? Explain.
