Do people even buy CDs anymore? They must, because Half Price Books keeps stocking them. The budget-media retailer may not have a Cactus-like variety, but it usually has a few titles by most major artists, especially if they weren't big blockbuster albums. It also seems to specialize in CDs by artists you had almost completely forgotten about but who had one or two songs you'd pay two or three bucks for — hell, you'd do it with iTunes, except here you get a whole album. While you're there, don't forget to browse Half Price's vinyl selection, which is likewise better than you'd think. Or hell, pick up a book or two while you're at it.
