This mid-1980s commercial really lays it on heavy, caricaturing the characters you would find working in your local record shop. I guess this sort of marketing worked because it was about this time that the two small record stores in my hometown shut down for good. I tended to buy my records second-hand, so while I didn’t buy a ton of music, I usually bought from one of them and not a department store or mall record shop.
The owner of the store and the people who worked there were characters, but I would not have described them as greedy or overpriced. Usually the prices were right in line with what you could get at the bigger store, with the convenience of not having to get on the highway to get your music.
