When I worked at Best Buy in the late 90's, we were trained on the virtues of Monster AV cables, which they pushed because they were an accessory with high margins. I recall one time when a sales manager cut open a cheaper version of some cables and discussed how it had less wiring and insulation, which I think he did with Monster cable to show the drastic difference. I think they had like 3 levels of quality, the cheap stuff, the mid-grade stuff and Monster. Even though I worked there I only ever bought the mid-grade because the quality to price ratio was great.
