Joe makes an offer to sell an order of produce to Bud for $550. It is a great deal and Bud jumps at the chance to accept Joe’s offer. Before Bud can get the money together, Joe sells the tractor to Sal because he needs the money right away for a down payment on a tractor. Is the contract between Joe and Bud enforceable under the UCC? If Joe and Bud have an e-mail exchange that documents their agreement, does this change your answer? Why or why not?
