If you would like to update your loyalty card details you can do this by creating an online account with the same email address used to sign up in-store.
If you don't have an email address or didn't provide one when you signed up, you will need to visit your local store or contact customer services to get these details updated for you.
Once you have logged into your account, you can verify that your loyalty account has successfully linked up with your new online account by going to "My Account" then clicking "Rewards for life"
If this displays your Rewards for life card number, then this has been successful and you will be able to update your details in the "My Details" section of your account.
If however, your Rewards for life details are not visible on your online account, please refer to the below article and get in touch.
