Once an order has been placed on Vitacost, it may not be possible to cancel or change it. Vitacost processes orders quickly to ensure efficient delivery, and this often means that customers have a limited window to make any adjustments. However, if a cancellation or change is necessary, it is advisable to act as swiftly as possible. Customers can typically find relevant information regarding order modifications on the Vitacost website, where they may have specific guidelines on how to handle such requests. If an order cannot be canceled or changed, there are usually options available for returns or exchanges once the items have been received. It is always a good idea to check the most current policies directly on the Vitacost website for the most accurate information.
