Please be aware that if you have requested next day delivery your order will be picked almost immediately so unfortunately cannot be changed. Orders for standard delivery of in-stock items can be amended for up to 2 hours after the order has been placed.
However if the order has already been processed by our warehouse then unfortunately, no changes can be made. When you receive your order confirmation email, please check all details are correct, and if you see an error please contact us as quickly as possible.
