I'm working on an e-commerce site and I would like to know after the user has added one or more items to his cart and is not logged in he will be directed to a page. Will this page be the "login page" or "create account" page? As this is a new site it will have no registered users. I feel even though there are no users the right UX flow would be to direct him to a "log in" page and show "sign up" as an option. My colleague feels that we must direct them to the sign up page as there are no users, what is the right move here? What my colleague says is good only for a temporary basis until we have users post which we must show the sign up page. On another case say if the user is logged out because his session has timed out and has to re-opt in by using his password, even in such a scenario it is better to show the "log in" page.
Your thoughts on the question and what would be the right method to follow.
