Lumens.com typically allows customers to cancel their orders within a certain timeframe after placing them, often before the items have shipped. To determine if your specific order is eligible for cancellation, you may want to check the order confirmation email for any relevant instructions or deadlines. If the items have already been processed for shipping, it may not be possible to cancel the order, but there could be options available for returning the items once they arrive. It is always advisable to review the return policy outlined on the Lumens.com website for further details about returns and cancellations. You may also find the contact information on the current web page if you have additional questions. This will help you better understand your options and make an informed decision regarding your order.
