Reduce monthly costs

The Cox website only provides UPGRADES available.  There is no way to see options for reduced services.  I'm paying $72/mo for TV "advanced," and while I do want DVR and On Demand, I don't watch all that many cable channels (I also have HBO and Showtime).  My latest bill was $202, which does include internet (but no phone).  Does anyone have counsel on what might be available to get this monthly number to go down?  Thanks.
