You can cancel an order from the App or Website by going to the Orders tab on the app or by clicking on 'My Orders' under the account page on the website. Once you select an order you will have the option to cancel it if it is not already processed by the store. If you do not see the cancel option, you can contact the store and see if they are able to cancel it if it is not already packed or dispatched for delivery. A restocking fee may apply for canceled orders.
