Once you've placed a Click and Collect order, we're unable to change the store of collection. If you need to amend this, you'll need to cancel your order or, allow your order to expire and we'll process your refund after the collection window has lapsed. You'll then need to place a new order from your preferred store.
Details of how to cancel your order can be found here.
You can also extend the collection date on most Click and Collect orders, allowing you more time to pick up your item(s). For details of how to do this, click here.
