Porko, Inc., is an OK firm that makes and sells custom tofu products. Veggietown, Inc., buys and sells food products from and to retail operations and food brokers. In July, Middleman, Inc. arranged an oral contract between Porko and Veggietown, under which Porko would ship $3$ orders to Veggietown. Porko shipped the goods to Veggietown and sent invoices listing the quantity of the respective order, price of the respective order, and all signed by Porko to Veggietown. Upon receiving the goods, Veggietown paid Porko only for the first two orders $($ $$25,000$ and $$30,000$ respectively$),$ not for the third. Porko files suit for breach of contract and seeks to recover $$35,000,$ the cost of the third order.

Even though the $K$ between the parties was oral, can it still be enforced? Why or why not?
