Unless you have an in house tech, the cable costs US money? Why should I give you something that belongs to me just because you feel entitled to it?
I charged $35 for extra cabling and laughed (after I left the customer's home, of course) when people said they would just go buy it and install it themselves at walmart. You are not gonna get a quality splitter and RG6 at walmart for less than $35, and then you have to do the labor on your own.
$35 is peanuts, and if it is peanuts for me, then I know it is peanuts for somebody in a quarter million dollar house with 2 HDTVs. Get over yourselves, guys. Personally, I don't want ANYTHING that is free, because it is generally worth what you pay for it.
