Already registered or validation message
If you receive a message when clicking on the Validate button, "The number you provided is already registered".
Try logging in again as it appears that you are already registered for an online account. You may receive the error message if you have signed up online as an online account will be created for you as part of the sign up process so you don't need to validate your membership.
If you receive a message when clicking on the Validate button, "Please go to your warehouse for validation". It would appear that you have entered the wrong membership number, please try entering your membership number again.
