When first visiting the WBC, you will be asked to enter the site password in order to even view the products. You should have received this site password in an email when first setting up your account, but if you cannot find it, feel free to submit a ticket to get the password.
Once you are on the site and able to view products and prices, you will not be able to check out until you have logged into your own account as well. You should have received an account invite email when you first joined which has instructions to set up your password and log in.
