Currently, if a user who is NOT logged in clicks the "Checkout Now" button, they are taken directly to the registration page. This is not good as some customers (particularly elderly) who already have accounts tend to enter all of their information AGAIN only to be told "That email address is already in use." They simply don't read the "Already have an account? Click here to log in!" text at the top.
90% of our support calls are due to this very issue.
To alleviate this problem, we'd like users to be redirected to the login page (signin.aspx) if they are not logged in when they attempt to Checkout. There doesn't seem to an AppConfig for this behavior, so if I have to modify the source, I'm fine with that if someone can point me in the right direction (we DO have the source code, btw)... or if anyone else has a solution to this.
I'd appreciate a quick response, as I'm stepping down from this position at the end of the week and my employers will up the creek without a paddle afterward.
