The last time I bought anything at a Pest Buy, I was helping a friend with an HDTV installation, and he needed an HDMI cable and he wanted it right away. The “Monster Cables” they had on display weren’t long enough for his layout, so I asked a salesdrone if they had any longer ones. He went in the back and came out with a no-name cable of the right length at a fraction of the Monster price. The only thing monster about Monster Cables is the size of the rip-off.
More than anything else, I hate the throbbing aural assault of Hip-Hop “music” you experience when you walk in.
