Clean Machines Company makes washing machines. Over the phone, Clean offers to sell Dealers Appliance Outlet one hundred model EZ2000 washers at a price of $150 per unit. Clean says that it will keep the offer open for ninety days. Dealers responds that within two or three weeks it will decide whether to accept. One week later, Clean faxes, and Dealer receives, notice that the offer is withdrawn. Dealer immediately phones Clean to accept the $150-per-unit offer. When Clean refuses to deliver at that price, Dealer files a suit. Clean asserts, first, that there is no contract and, second, that if there is a contract, it is unenforceable. Discuss Clean's assertions.
