UPDATE! Just got off the phone with COMCAST and they charge $69.95 for three outlets. If the house is wire inside it's $24.00 for each additional connection. (4th, 5th, etc.) COMCAST RECOMMENDS DO THE WHOLE HOUSE AT INITIAL INSTALLATION. It's cheaper than calling them back at another time. If the house needs additional wiring inside (New Outlet) its $59.95 per outlet. The basic cable is $16.95 a month.
