Neiman Marcus typically allows customers to change or cancel an order after it has been placed, but certain conditions apply. Once an order is confirmed, the ability to modify or cancel it depends on the current order status and how quickly the request is made. If the order is still in processing, there may be a chance to make changes or cancel the order by contacting customer service. However, once an order has entered the shipping process, it usually cannot be altered or canceled. It is advisable to check the website for specific order management options, as they frequently provide resources and information that can assist customers in handling their orders effectively. For the most accurate and up-to-date information, visiting the current web page is recommended.
