Sonja owns a bakery in San Francisco.

Performance of Sales Contracts.Sonja orders two new model X23 McIntyre ovens from Western Heating Appliances for $16,000. Sonja and Western Heating agree orally, on the telephone, that Western will deliver the ovens within two weeks and that Sonja will pay for the ovens when they are delivered. Two days later, Sonja receives a fax from Western confirming her order. Before delivery, Sonja learns that she can obtain the same ovens from another company at a much lower price. Sonja wants to cancel her order, but Western refuses. Is the contract enforceable against Sonja? Why or why not? ( Please base your response on the law and not personal opinions)
