2. On January 3, Gray sends Brown the following offer by email: "I offer you my vertical milling machine in the same condition it was when you last saw it for $4,200. This offer will remain open for your email acceptance until January 15.\" On January 9, at 10:00 A.M., Brown sends the following text message via a smartphone to Gray: \"I accept the offer of your vertical milling machine for $4,200. Am sending truck for it immediately.\" Is there a contract? Why or why not? 3. Expanding on question 2, assume that Brown received a withdrawal from Gray at 9:00 A.M., January 9, but, be- cause the original email stated that the offer was open until January 15, Brown sent acceptance by email an hour later. Was there a contract? Why or why not? 4. Referring again to question 2, assume that Brown's text message acceptance on January 9 was not delivered due to a connection loss and not noticed and redeliv- ered until January 16. Was there a contract? Why or why not
