When it is clicked I want the custom tab SHOP NOW page to open.

Can this be done and how please.

If you want to redirect the user within the Facebook Page tab iframe, then depending on your website language you can easily achieve this. In PHP for instance: header("Location: my_page.php");

Otherwise, if you want to redirect the user to your website outside Facebook, you use something like:

<script>top.location.href="http://example.com/page.php"</script>
