A consumer purchased a sofa from an online retailer, and ordered some customization of the sofa. The retailer contacted the consumer a week later and told the consumer that there were delays at the manufacturing facility, and that the product would arrive late. The retailer included in that message a notice that purchases could not be canceled once they were in shipment to the customer. The customer thought about it, then decided to cancel. The retailer responded that they could not cancel an order for a custom product once the manufacturer had started production, and that work had begun on the sofa.
Can the consumer cancel the sale? Is the statement in the first email, that cancellation is possible prior to shipment, binding?
