Best Buy charges $500 to hang it. I paid $400 with the AAA coupon (they didn't even verify membership)
They'd go through the brick behind the TV and then fish from there.
They charge a $100 consultation fee, that is refunded if they do the work.
So, I paid $100, they came over and took a look at it. The said no problem. I bought the TV and paid for install etc which was $400 with the AAA coupon (which I think I may still have an electronic version of I can send you if you want it). They refunded the $100 for the consultation, so it was $400 total for install.
Their install includes programming of the remote (I used my Direct TV remote to turn on/off the TV, Volume etc). They also hook up the surround sound, DVD player, cable/direct TV box etc. so be sure to have the proper cables and such and they'll run them all at once (I had them run my HDMI cables and an extra one in case I need it in the future)
Well worth it IMO, nice to let them in the door, go about your business and come back and the TV is hung and programmed etc.
