You are a seller of farm equipment. Sidney Lanier puts in an order for a new combine harvester, which costs $425,000. Under the terms of the agreement, Mr. Lanier has to forward you a certified check for 25% of the purchase price within 15 days of the signing of the purchase agreement. Meanwhile you are preparing the combine harvester for shipment to Sidney Lanier's farm. On the 15th day, you do not receive a check from Mr. Lanier. You do not receive a check on the 16th, 17th, or 18th day either. Meanwhile, another farmer has come into your office to ask about buying the combine harvester.
What can you do in this situation?
A. Since you and Mr. Lanier have a contract, you have to wait until he sends you the check before you can do anything.
B. Mr. Lanier had a duty to send you a check by the 15th. He's breached that duty under the contract, and it appears to be a material breach, so you have the right to rescind the contract.
