HarrietCarter.com typically allows customers to cancel or change their orders, but it is important to act quickly. Once an order is placed, it generally enters processing shortly thereafter, making it difficult to modify or cancel after a certain point. For cancellations, customers are usually advised to review their order confirmation email for any specific instructions. If the order is still in processing, cancellation or changes may be possible. However, if it has already shipped, the order will need to be returned according to the store's return policy. It is always a good rule of thumb to double-check the details of the order before finalizing the purchase to avoid any potential issues. For the most accurate and up-to-date information regarding order changes and cancellations, it is advisable to look directly on the current web page or check the order confirmation details.
