Yes, you can change your delivery slot or edit your order after checkout. For most orders, you can change the slot or place a Next Day delivery until 8pm the day before delivery and amend until 9pm. The cut-off for amending orders will be clearly displayed after you checkout and on your My Orders page.
We recommend editing your order as early as possible and not too close to the order deadline time to avoid any issues. Entertaining/Food Made to Order items have a required number of notice days, so if you have an Entertaining product within your order, we recommend calling us on 0800 188 884.
