While we process your request the moment we receive it during business hours, it is sometimes very difficult to get cancellation requests complete. Our network ranges throughout the country and because of the importance placed on a timely delivery of your request and various time zones, it can sometimes be very difficult to stop or cancel a delivery attempt or a placed order. Cancellations must be done prior to delivery, and in all cases within 24 hours or placing your order. Any cancellation requests after this period cannot be guaranteed and are subject to a 20% charge.
