Who isn't a sucker for a good sale? Seems like Zia always has CDs marked down -- and not just older titles. If you stop by with a shopping list of some of the most in-demand new releases, chances are you'll snag some for a couple bucks less than you'd expect. Better yet, Zia has an overwhelming selection of used discs, which are handily filed right along with brand-new ones. So while you may not take a chance on something for, say, 15 bucks, if the asking price is seven or eight, it's a lot easier to be open-minded.
