To change the delivery date you booked, you can contact the supplier that's delivering your product. To allow enough time, you should try to get in touch no later than 24 hours before the delivery date. To find their contact details, look at the confirmation email you received after ordering. If you still can't find their contact details, you can talk to us on live chat. A live agent is online at these times: Weekdays, 8am – 6pm Saturdays, 8.30am – 4.30pm Our chatbot is here to help outside of those times.
