Though the 45 isn't the hippest musical format on the market, those seven-inch slabs of plastic are still coveted by collectors across the country. As such, stores catering to this clientele continue to exist in most major cities, with prices for used singles generally starting at several dollars and skyrocketing from there. Wax Trax, however, contains box after box after box of 45s priced as low as a quarter; most of the others are fifty cents. The charges for long-players are usually on the low end of the scale, too, which helps explain why vinyl lovers who travel to Denver make a beeline for Wax Trax. Those of us who live here have a lot less distance to cover to take advantage of a local treasure.
