If you're cancelling an order on the website, select ‘My orders’ at the top of the page and then ‘Orders due for delivery.’ You'll see a list of all your orders, including Click+Collect. Find your order in ‘Orders due for delivery,’ then select ‘Cancel this order’. Select ‘Yes’ to confirm.
To make an order cancellation via the Tesco Grocery & Clubcard app, select ‘My orders’ from the left-hand navigation and you'll be able to cancel your order from there.
If you're amending your order, you won't have an option to cancel. To cancel your order from here, checkout your order or select 'cancel changes' – this will close the order and allow you to cancel it. You'll receive an email to confirm the order has been cancelled and you will not be charged.
