Don’t know how much you paid at RS, but any cable at Best Buy is priced 3 to 5 times higher than what you can get the same piece for on Amazon. NEVER by cables at Best Buy.
BBY has some amazing items in stock though, the 75 inch 4D ultra high resolution and curved TV’s are stunning. They are at least trying to say in the game, RS is run by a bunch of shyster clowns.
I was helping a friend with an HDTV installation and needed a cable. Went to a Best Buy and looked at their selection. They were all overpriced Monster cables, and none of them were long enough anyway. I asked a salesdrone, and he went in the back and came out with a cable of the right length that was a fraction of the Monster Cable price.
The worst part of Best Buy is the constant oppressive throbbing of hip-hop “music” that fills the store and assaults you as you walk in the door.
