If you currently have a Choicelunch account, and are attempting to create a new account, the system will not allow you to use the same email address that you previously used for an account.
To get around this, please use a "dummy" email address for this input field, and then contact Choicelunch Customer Support at customerservice@choicelunch.com or at 855-GO-LUNCH. Your Customer Support Team will link your email of choice to the new account created.
