Suppose | Compare Cable, Satellite & Streaming TV Services ... you select the channels you REALLY want and the site will give you the best choices for you ...for instance, Directv Now now has a $40/month package with over 50 'Cable' channels for $40/month but there are many other choices
hope this helps
