Need help with changing plan and cutting cost

My tv/internet plan has increased about $26 monthly.  I do have an old plan (select double plan), but something tells me if I change it, it's going to cost me even more.  The tv boxes are $14 and we have 4 - $56 for them alone is crazy!  We are at the mercy of Comcast unless we go streaming only, which I hesitate to do.  Can someone help me directly with this?  I've been a Comcast customer for 4 years! Thanks!
