On March 10th, Buyer went to a local store to purchase a new iPhone 13. He told the Seller that he liked one in particular, but needed some time to think about it. The Seller said there was no rush and wrote down his offer for the iPhone at $1300 and agreed to keeping the offer open for 15 days. On March 13th the Seller changed his mind and sent Buyer an e-mail revoking the offer, which Grover received immediately. On March 14th, Buyer sent a reply e-mail accepting the original offer. Is there a contract? Explain and include an analysis of offer, acceptance and consideration.
