I have a Directv account in my name (not for me, for my aunt) and I was signing in to pay the bill and noticed the 72 Local swap message. So I called in and they said I do qualify for the free 72 local swap. So what they did was made me get a hd receiver and replaced my national feed satellite. They said it was free since they require it. Two questions what is the 72 local swap like where do I get more info and do I still need my aunt to keep the local dish up still?
