One other option is to set a session variable when you're checking rights, and displaying that on the login page.

So you could do:

if(!User.IsInRole("shopper"))

    session("denied") = "You don't have access to shop";
    response.redirect("/login");
}

if ( session("denied") != "" ) {
   message.text = session("denied");
   session("denied") = "";
}
