If your account goes to the correct distributor sign-up URL, they will not be required to enter their credit card info. If they are being prompted to enter their credit card during sign up, it means they did not start the process from the correct URL. If you are trying to sign up with the account on location from your PC, make sure you go back to the correct distributor sign up URL after each location signs up under your distributor URL.
To ensure that you are at the correct distributor sign-up location, we have added the distributor logo to the sign-up screen.
