We aim to dispatch orders as soon as possible once they have been placed. Therefore, we are unable to make any changes to your order once received. This includes changes to the delivery address, email address, cancelling the order or adding or removing items from the order.
However, you have 30 days after delivery to return your items for a refund.
If this is for a Subscribe & Save order please read this article that may help here : How to cancel your subscribe & save order for an item
